Evaluation of Genetic Potential of Cotton Lines against Whitefly Tolerance

Cotton (Gossypium hirsutism L.) is a primary source of natural fiber, fuel, wood, and oil worldwide an essential raw material for the textile industry. Whitefly (Bemisia tabaci) one major pests distributed has broad genetic diversity. In this research, diversity in cotton germplasm was explored against whitefly infestation. Broad sense heritability common approach used to detect association inheritance target trait. Maximum (PIC 0.96) minimum 0.36) polymorphism by SSR primer NAU 988 5121, respectively, with average value 0.73. Pair-wise estimation ranged from 0.500 1.00. Neighbor-joining (NJ) tree, based on UPGMA (Unweighted pair group method arithmetic), grouped genotypes into six main clusters, i.e., A, B, C, D, E, F. accessions fall single cluster showing low among them. The upland FH 326, SLH 07, FH18, Cris 541, showed divergence rest might have resistance attack. Our results also explain utilization markers explore its breeding program.
