Abstract:
The level of genetic diversity is an essential element of sustainable crop improvement. With the main objectives to facilitate direct selective breeding and conservation of germplasm resources, the genetic diversity of 308 elite upland cotton (Gossypium hirsutum L.) genotypes was studied using 195 simple sequence repeat (SSR) markers. In this study, the total number of SSR alleles, average number of polymorphic alleles per locus, polymorphism information content (PIC) per locus, genotype diversity index (H’), pair-wise genetic distance similarity, and UPGMA clustering will be determined and analyzed. The study would provide useful guides for efficient utilization of the existing genetic variations to address the issue of narrow genetic-base challenging improvement of upland cotton for fiber yield and fiber quality worldwide.
Key words: Upland cotton, genetic diversity, SSR markers
