Developed Through Induced Mutation and Hybridization]]>KandhroMuhammad Mureed Sawan Laghari Mahboob Ali Sial Ghulam Shah Nizamani 5200215Two early maturing mutant strains viz. AENB-10/87 AENS-18/87, and a hybrid strain AEH-2/90 along with two commercial varieties; NIAB-78 and Rehmani were evaluated in zonal varietal trials. Genotype AENB-10/87 produced the highest seed cotton (2270 kg ha-1) yield over all environments followed by AENB-18/87 (2193 kg ha-1) and had the high regression coefficient (b=1.106 and 1.108, respectively) and deviation from regression (S2d) value (1551.305 and 2759.45, respectively) showed specific adaptation to poor environments. NIAB-78 with comparatively better yield had b value close to unity and lowest (S2d) value indicating wide adaptability over the environments. The data indicated that AENB-10/87 followed by AENS-18/87 produced significantly higher seed cotton yield than AEH-2/90 and Rehmani at 3 out of four sites and ranked 1st and 2nd, respectively when averaged over all sites. AENB-10/87 also produced significantly higher number of bolls/plant, seed cotton yield/plant and ginning outturn percentage (GOT%) than the commercial varieties, whereas, it was at par with NIAB-78 in case of boll weight and staple length.]]>Fittouh, H.A.A.E., J.O.
