Biotechnology requires germplasm, as both raw material and a source of natural variation. As a way of shaping and using genetic information, biotechnology has implication for germplasm conservation and use. This chapter discusses these opportunities and the allocation of resources.

      INTRODUCTION. Cotton (Gossypium spp.) is the world’s leading natural textile fibre crop and a significant contributor of ting of 50 species with different levels of ploidy, Gossypium has long served as a model for studying fundamental biological questions on genome evolution, plant development, polyploidization and crop productivity ().Cited by: Gossypium herbaceum, commonly known as Levant cotton, is a species of cotton native to the semi-arid regions of sub-Saharan Africa and Arabia where it still grows in the wild as a perennial shrub. [clarification needed] It is a sister-species [clarification needed] of Gossypium : Malvaceae.

The success of a germplasm survey, either for studying genetic diversity or for collecting nuts for a germplasm collection, is largely governed by the choice of sample population.

Ideally, it is best to identify and collect as much genetic variability as possible.

Since the availability of viable seed cannot always be assured during botanical expeditions, a simple tissue culture method was developed to allow the collection of living vegetative material from the field.

We used a high-throughput genotyping platform to appraise the diversity of cultivated cotton and its wild relatives (Additional file 2).Of the SNPs identified in this study, 33, (86%) were polymorphic across all Gossypium species measured (Table 1).From sequences specifically selected to detect Cited by: cotton germplasm collection with a wide g eographic cover- age represented by 4 continents, ~33 geographic regions, and ~ countries (T ables 1, 2; Fig.

Recent studies have suggested that cottonseed (Gossypium spp.) has the potential to contribute to the effort against world hunger, particularly by providing a high‐quality protein report analyzed the diversity in protein content and other seed quality factors in the U.S. National Cotton Germplasm Collection.

The Gossypium barbadense L. germplasm collection contains over accessions listed in The National Collection of Gossypium Germplasm cotton, a distinctive type in which the seeds of each locule are conjoined into a single kidney‐shaped mass (kidney seed), represent more than 20% of the photoperiodic, shortday stocks in the barbadense collection.

Such a germplasm collection is known as a recue collection. This collection and conservation are done in the case of a danger of genetic erosion or extinction of target species. Reasons for Doing Rescue Collection: Agricultural change: Traditional major crop may be seriously threatened by the introduction of uniform, modern, or exotic varieties.

Plant Germplasm The National Plant Germplasm System (NGPS) is a collaborative effort to safeguard the genetic diversity of agriculturally important plants. The mission of the NPGS is to support agricultural production by acquiring, conserving, evaluating, documenting, and distributing crop germplasm.

However, a vast majority of the cotton collection remains untapped because of technological limitations. With the development of DNA markers and other molecular tools in cotton, we present our new strategies on the characterization of Gossypium germplasm.Analysis Method: bin markers out of the markers mapped on a consensus map, the consensus map was JoinMap derived from 3 populations: a) Phytogen 72 x Stoneville F2, b) Phytogen 72 x Stoneville RIL, and c) Stoneville x Phytogen 72 RIL.
