Resumen
Descripción
Evaluation of 35 genotypes of tomato for yield, quality and fruit characters under net-house revealed that PCV washigher than GCV for most traits. High heritability, with moderate to high GCV and genetic gain, was recorded fornumber of fruits per plant, yield per plant, fruit weight, number of fruit-clusters per plant, polar diameter and numberof flower-clusters per plant indicating, that, these characters could be improved by simple selection. Total yield perplant had positive and highly significant correlation with number of fruit-clusters per plant, number of flower-clusters per plant and fruit weight. Number of locules per fruit showed positive and significant correlation with fruitweight and equatorial diameter but, significant negative correlation with polar diameter. Maximum direct contributionto total yield per plant was made by number of fruits per plant, followed by number of locules per fruit.
