Molecular Dissection for Boll Shedding in Upland Cotton Using Microsatellites

DNA markers application in marker-assisted breeding of cotton is handicapped due to low genetic diversity germplasm. The present study was designed identify markers, predominately simple sequence repeats (SSRs), associated with tolerance/resistance heat stress as a consequence boll shedding. To find out the total 24 genotypes and 50 SSR primers were used. Total 288 alleles produced an average 5.7 per primer. Bootstrap cluster analysis used generate dendrogram that accessions into two main clusters. Eleven fall single cluster. Phenotypically H-4074 gives more diversity, while genotypically sheared same background H-4070, H-4091 H-4090. Low observed among both genotypic phenotypic maximum varieties group. This helps for selecting diverse multiple traits, which drought It suggests further elaborating molecular by using new marker improve yield cultivars. These preliminary results set stage initiating depth marker-trait association studies, will be instrumental cotton.
