Google Scholar. Diversity in plant genetic resources provides opportunity for plant breeders to develop new and improved cultivars with desirable characteristics, which include both farmer-preferred traits (high yield potential, large seed, etc.) Dhruba Thapa. This phenomenon, which is also a part of the evolution process, allows the organisms to adapt to changing conditions and to survive.

While the importance of these forces is widely accepted (8), there is uncertainty about the relative strength of demography and dispersal in shaping genetic structure across global environ-mental gradients (9, 10).

Summary measures of genetic diversity in cultivated plants and their wild relatives are needed to guide managerial decisions, to monitor progress and to warn of emerging problems in agricultural production.

It is a simple and quick methodthat combines most of the advantages of microsatellites (SSRs) andamplified fragment length polymorphism (AFLP) to the universality ofrandom amplified polymorphic DNA (RAPD).

The entire population of plants would die because none would carry genetic variants that might confer resistance to the virus. SPRINGER. sible to conserve all plant genetic diversity in genebanks, that readily access to genetic diversity by its users (i.e. Genetic diversity in the germplasm of black pepper determined by EST-SSR markers B.D. Greater genetic diversity in plants gives them a remarkable ability to adapt to sudden environmental changes (Raza et al., 2019; Wu, Cai, Zhang, & Zeng, 2017). Reciprocal recombination arises via the exchange of genetic information between two nonsiscer chromatids. (1992) and Hamrick and Godt structure of cytoplasmic genetic diversity in annual or (1996) on a large number of species, indicate that trees short-lived plants are very rare.

Genetic diversity is the variation occurred in genetic information, which depends on frequency and diversity of alleles among individuals within a population or a species. Selection is based on the relative economic importance of these plants on the medicinal and pharmaceutical levels. germplasm is essential for the conservation and utilization of plant genetic resources [13]. If a fatal virus infected the plants and began killing them, what would ultimately happen? Rudra Bhattarai. Individual species have similar characteristics, however, they are not absolutely identical with each other. While the usefulness of molecular tools to describe genetic polymorphisms and the importance of generic resources in agriculture has been largely covered in the literature, we felt the need to highlight how the Diversity in plant genetic resources provides opportunity for plant breeders to develop new and improved cultivars with desirable characteristics, which include both farmer-preferred traits (high yield potential, large seed, etc.) To changing conditions and to survive microsatellites ( Box 74 ) are the most frequently used markers are....
