Abstract:
In the present investigation the number of clusters and average fruit weight were positively associated with fruit yield per plant in all the three F2 populations, while number of fruits per plant was also positively associated with fruit yield per plant in all the populations except F2 population of TSH-8. Plant height recorded significant negative correlation and positive direct effect in all the populations. In all the F2 populations number of clusters recorded negative direct effect on fruit yield per plant, whereas fruits per plant recorded positive direct effect. Average fruit weight exhibited positive direct effect on fruit yield per plant in all the F2 populations except F2 population of TSH-2 hybrid. The information obtained helps in revealing proper weightage to the various characters during selection or other breeding programme so that the improvement of desirable traits can be achieved effectively.
