Abstract

Direct selection for yield will not be the best strategy for an effective crop improvement programme. So selection of traits which are highly positively correlated with yield and have direct effects on seed yield will be the most effective method for improvement of yield and its component traits simultaneously. In the present investigationyield/plant had significant and positive association with the characters viz. number of capsules/plant, number of seeds/capsule, 1000-seed weight, capsule length and plant height where as it had no significant negative association with any character. Number of capsules/plant had the highest significant direct positive effect on seed yield/plant followed by number of seeds/capsule and 1000-seed weight. The highest significant positive indirect effect on seed yield was observed by 1000-seed weight via number of capsules/plant followed by number of seeds/capsule via capsules/plant.

Keywords

Association, Direct effect, significant, indirect effect

Conclusion

Number of capsules/plant is the most important trait which has positive significant association with seed yield/ plant as well as highest direct effect for seed yield/plant. The other yield attributing traits like number of seeds/capsule and 1000-seed weight also have positive significant association with yield as well as considerably high positive direct effect towards seed yield / plant. Hence selection for these yield component traits will definitely help in improving the seed yield/plant.
