- Abstract
The study was conducted at the experimental research farm of Central Cotton Research Institute, (CCRI) Multan and Punjab Seed Corporation (PSC) Farm, Khanewal, Pakistan on 48 cotton (Gossypium hirsutum) genotypes i.e. 12 parents and their 36 F1 hybrids at two locations to find out direct and indirect effects of fiber traits on seed cotton yield using path coefficient analysis. Results showed that GOT percentage had positive direct effect (0.734) on seed cotton yield at Khanewal location while negative direct effect (-0.03) at Multan. The indirect positive effects of GOT percentage were found for fiber strength (1.785) and fiber uniformity index (0.187) while negative indirect effects were observed for upper half mean length at both Multan and Khanewal locations. Fiber length exhibited positive direct contribution (3.272) towards seed cotton yield for Khanewal while fiber length had negative direct effect (-0.218) for seed cotton yield at Multan. Fiber strength indicated positive direct effects (0.798) towards seed cotton yield at Multan while negative at Khanewal location. The negative direct effects (-0.421) were shown by micronaire value towards seed cotton yield at Khanewal while positive (0.265) at Multan. Micronaire value depicted positive indirect effects for fiber strength and fiber uniformity index at Khanewal, while at Multan it is positive for fiber strength and negative for FU index. The upper half means length showed positive direct effects (1.207) on seed cotton yield at Khanewal while negative direct effects (-0.529) at Multan location.
