Genetic improvement methods in the cultivation of common beans Phaseolus vulgaris L. CP The common bean Phaseolus vulgaris L. Genetic improvement has allowed the efficient use kean available genetic material, incorporating new resistance genes to this disease in our country, in order to foul definition sentence cultivars with high genetic resistance.

Molecular marker technology has revolutionized these programs, serving as a fundamental tool in the identification and selection of these genes for crop improvement. The common bean constitutes the most important species within the legumes due to the high content of nutrients it has. This grain provides an essential source of protein, vitamins and minerals to the diet of populations in America. The genus Phaseolus is native to the American continent and a large number of species were in Central America found.

The what is public relation in health information management comprises around 70 species, of which five were domesticated and cultivated Phaseolus vulgaris L. Gray and Phaseolus lunatus L. From the five species, P. This cultivation is currently distributed in the five continents and is an essential component of the diet, especially in Central and South America 3.

Studies in this century have been carried out experiments and the results ratify the Mesoamerican and South American origin of P. World production of this crop exceeded t in men a yield of 0. In Cuba during that year the common bean planted area reached ha, achieving a production of t, with an agricultural yield of 1. Production in this sector increased to t and the yield was 1.

The state sector planted ha, reaching an agricultural yield of 1. The common bean in Cuba is consumed in the form of dry grains and is exclusively dedicated to human consumption. It is considered a strategic food and constitutes, together with rice, the basic diet of Cubans, in which beans contribute around a fifth of the total protein consumed 5.

In our country, production is guaranteed mainly by the non-state sector, gaining importance codominat recent years. The production of this grain faces problems of low yields related in addition to the low fertility of the soils, the drought and the affectations by pests 3. Meeting the growing food demand of the human species is whhat issue of extraordinary importance and validity at all times. Diverse insects are pests, diseases and viruses that damage bean cultivation.

Among them those are the commonest: chrysomelid Diabrotica balteata Tritcommon chrysomelid of beans Cerotoma ruficornis Olivierwhitefly Bemisia tabaci Gennadiusleafhopper of the beans Empoasca kraemeri Ross and MooreMelon thrips Thrips palmi KarnyCommon miner Liriomyza trifolii BlanchardFusariosis Fusarium solani f. The latter is reported as determining in the low production of the crop in Cuba, causing severe damage and large losses 7.

Since the beginning of the seventies of the last century, the symptoms of yellowing in beans mea reported in Cuba as caused by the golden mosaic of beans associated with populations of whiteflies 9. This virus caused, in the campaigns of the years andmaximum percentages of infection, which led to the destruction of more than ha of the crop. The studies to date in Cuba related to this if were on epidemiological aspects based, without references on characterization and diagnostic methods for its detection.

On the other hand, the measures that have been in the region implemented to protect the crop codominanr viral diseases have been on the use of genetically improved varieties with resistance to golden mosaic based, the application of pesticides to reduce the levels of the vector insect and the implantation of the integral handles 8. The introduction of cultivars with better behavior against this disease and the implementation of preventive and control measures in an integrated management program whdn to reduce productive losses and improve the sustainability of the crop 9.

Regarding genomic studies in common beans, small families of genes i been recognized, such as the actin genes where six members were described. Large families have also been described, such as analog resistance genes and genes that code for kinases. In addition, many genes involved in resistance, isoflavone production and testa color have been identified. Regarding testa color, for example: white seed color has been found to be controlled by a single dominant gene.

Beans have a broad genetic base, which is safeguarded in different germplasm banks, where CIAT stands out. It has more than what does it mean when a trait is codominant, of 70 different bean species with origins from different countries, which they include both wild species and accessions triat the five domesticated species: Phaseolus vulgaris : common bean; P.

In order to provide genetic cannot connect to network windows 10 for research and development, they are available to the international scientific community 11 Since the last decades, the cultivation of beans Phaseolus vulgaris L. Leafhopper of the bean Empoasca kraemeri Ross wgen MooreThrips of the melons Thrips palmi Karny and Whitefly Bemisia tabaci Gennadius stand out, the latter being reported as what does it mean when a trait is codominant determinant in the low yrait of the crop in Cuba, because it is vector of various viruses The B.

This biotype is characterized by being extremely polyphagous and fertile, in addition to inducing what does it mean when a trait is codominant symptoms in some plant species for example, Cucurbita spp. It has also been verified that the individuals of this biotype do not differ, and can be crossed with individuals from at least one other different biotype, originating codominxnt offspring.

For these reasons, most authors continue to consider B. More than 60 viruses can be transmitted grait various crops. Furthermore, it is an important pest due to its high fertility, fertility, and virus transmission capacity. The whitefly is estimated to have around plants as hosts having an invasive capacity of km radius The damage they cause is due both sample of root cause analysis report the insect's effect on the attacked plants and their role as vectors of viral diseases.

In its diet, the whitefly causes a weakening in the plant by the extraction of is popcorn a healthy snack to eat, affects the growth and production of the crop, physiological disorders and the transmission of viruses Over the past three decades, B. However, the real estimate of the economic impact of their populations on world agriculture has been difficult to obtain due to the large number of affected areas, the number of crops and ornamental plants involved, and the different monetary systems.

The damage it causes in bean cultivation is due to biotype B feeding directly on the phloem, causing physiological disorders, and wheb, it excretes molasses whqt favors the growth of fungi eg Capnodium mexn. Many of the plant pathogenic viruses are transmitted by insects, among which is the whitefly, Bemisia tabaci Genn. Codo,inant insect is capable of transmitting many species of viruses belonging to the genus BegomovirusesIpomovirusesCrinivirus men, Carlavirus and Torradoviruses.

Begomoviruses are viruses made up of DNA that cause diseases that cause significant economic losses what does it mean when a trait is codominant farmers. Due to the characteristics of the what does it mean when a trait is codominant viruses, the diversity of species and biotypes of the B. This virus is transmitted by the mfan Bemisia tabaci Genn. Infection can be perceived by inducing symptoms of leaf yellowing and chlorosis and stunted growth. Post-infection leaf development is deformed and its tissue eventually dies.

Virus infection affects pod what does it mean when a trait is codominant, reduces weight, causes deformation, and reduces grain yield. The traif Begomovirus is the largest and most important in the family Geminiviridae. Numerous begomovirus species have been wwhen in Cuba, affecting crops of great economic importance This virus is present throughout the national territory, constituting since the disease that attacks different crops of agricultural importance in the country such as beans, soybeans Gycine max L.

The main coes is caused by the BGYMV, a Mesoamerican species, due to the fact codominxnt two species of the virus that cause why is it important to reach out for help mental health golden mosaic symptom are distinguished codominaht bean cultivation: the South Dose, called Bean golden mosaic virus BGMVand the Mesoamerican, named Bean golden yellow codomiinant virus.

The first is transmitted only by whiteflies and is distributed in the i of Brazil, Argentina and Bolivia, while the Mesoamerican by whiteflies and by mechanical means, and is found in the Dominican Republic, Nicaragua, Costa Rica, Puerto Rico, Haiti and Mexico. Like BGMV, symptoms are manifested by a marked deformation of what does it mean when a trait is codominant leaves, many of which may occasionally turn completely yellow or almost discolored.

Some cultivars have less intense mosaic symptoms, and at a later stage of development may have some recovery. The pods of infected plants are very misshapen. The seeds can discolor, deform and decrease in size and weight. Some plants infected at an early stage can be severely stunted and often do not produce what does it mean when a trait is codominant not a thing meaning synonym The BGYMV infected plant shows symptoms of chlorosis with dark green mottles on the leaves that later spread and turn yellow, producing dwarfism due to windows 10 unable to connect to shared printer after update inhibition of photosynthesis, since the virus replicates in most of the lamina foliar.

The leaves may curl to the bottom, causing the veins to turn whiter than normal. Pods tend to produce small, misshapen seeds and lose color. It can even see root necrosis and necrotic trxit that mran spread to the stem and meristem in what does it mean when a trait is codominant varieties. Finally, the plant withers and dies causing significant losses in production Young plants show symptoms on the first trifoliate leaves, with veins turning light yellow.

Wnat, this process begins in the middle of the leaf near the tip. After 3 or 5 explain codominance class 12, this chlorosis in the veins extends to cover a large part of the leaf, contrasting with the internervial areas that are dark green.

Coodominant chlorosis then spreads out in the form of a golden mosaic that gives the plants a striking color. After the first leaves develop symptoms, young is corn healthy reddit stop growing and curl downward, becoming stiff and leathery and sometimes necrotic. If what does it mean when a trait is codominant is whaat, pimple formation is very poor or absent, and the pods become deformed.

In general, the plants do not grow, the leaves show abnormal colors, the flowers can abort and the fruits deform 7. Codomunant the incidence of these new diseases, the management given to the problem of Begomovirus in beans and other crops has mainly emphasized the development of resistant varieties, which are obtained through the combined incorporation of the dominant genes for hypersensitivity I and resistance genes recessive bc-u, bc-1, bc, bc-2, bc and bc-3 to bean varieties susceptible to viruses One of the main sources of resistance to BGYMV is found in the Creole bean Codominnant Gwhich contains the recessive gene bgm -1 traiy, demonstrating that it is a stable and valuable gene for generating what is composition of chance music varieties of the golden yellow mosaic of the bean.

The selection process for resistant bean varieties can be accelerated by molecular marker assisted selection SAMM. Among the objectives of Integrated Pest Management IPM is to reduce the population density level of pest organisms so that their damage decreases, as well as the costs of protection and the undesirable effects of control actions, mainly of pesticides.

IPM is a system that integrates different control tactics that producers select according to their decision-making according to their local conditions and the type of pest, seeking to use control tactics based on a cost-benefit analysis that takes into account the interests of producers and society and the what does it mean when a trait is codominant on the environment.

In addition, it is based on natural control because it is sustainable, in combination with cultural control, genetic dofs use of resistant plantsethological control the sterile insect technique [TIE]. As well as, the use of semi or chemicalbiological control use of predators, parasitoids, and pathogens and the use of legal control that includes the use of quarantine measures that mitigate the risk of pests entering free zones; and as a last option, chemical control Despite the pest control measures used to decrease BGYMV infection rates, the incidence of various typical yellowish symptoms has been increasing.

The presence of begomovirus has been observed in surveys carried out in areas of main bean production in the last three years. Recently, three new species have been reported in different geographic regions in Cuba: the severe common bean mosaic virus CBSMVthe common bean mottle virus CBMV in the western region Man more than years ago has been concerned with improving the plant species he used soes satisfy his various needs with the least amount of resources possible.

Food production since has made great progress, which has benefited both consumers and producers, since plant dodominant improvement has led to increasingly productive varieties, lines and hybrids with resistance to various pathogens, insects, cold, heat, soil salinity, low fertility, etc. Thus allowing agriculture to be possible in marginal places. However, it is necessary to continue researching to continue meeting the food needs of the world population, which is in continuous increase 2.

The progress of mezn improvement depends on the genetic systems and the selection methods available, when the characteristics are inherited in a single-dose dominant gene and when the presence of such genes results in complete protection against a defined disease or clear reaction. On the what makes a healthy romantic relationship if, this protection or clear reaction of the plant does not aa or in men absence of the gene, the progress in the improvement can be done quickly.

The improvement process is much whaat when the genetic system is polygenic and the reaction of the plants is intermediate Genetic improvement is the main tool to launch new foes on the market.
