Abstract

Twenty one elite lines of tomato were evaluated in Varanasi during 2010-11 to 2014-15 for important yield traits. Pooled analysis of variance revealed highly significant genotypic and environmental effects for all the traits. Variances due to genotype × environment revealed significant differences for number of fruits/plant and fruit yield/plant. Variance due to environment (linear) component was highly significant for all the traits. Variance due to genotype × environment (linear) was significant. The genotypes Kashi Amrit and Azad T 5 revealed stability for average fruit weight and the genotype H 24 for number of fruits/plant. The genotypes H 86, Kashi Amrit, Pusa Sadabahar were the stable genotypes for fruit yield/plant. The genotypes BT 120, NDTVR 60, Punjab Upma, Pusa Sadabahar were responsive genotypes for average fruit weight and the genotype GT was responsive for number of fruits/plant. The genotypes FLA 7171, Punjab Upma, Selection 7 were responsive genotypes for fruit yield/ plant.
