Stability of yield and its component characters in tomato (Lycopersicon esculentum Mill.)

Abstract

Eleven tomato (Lycopersicon esculentum MilL) genotypes were evaluated for yield and its components under eight environments. Variance due to genotypes, environments, genotype x environment and G x E (linear) components were highly significant for average fruit weight, fruit polar diameter, fruit equatorial diameter, number of fruits per plant, yield per plant, early yield per plot and total yield per plot. The genotypes F1-124, 5hivaji and 855-211 were found to be desirable and stable for total yield per plot, while genotypes 5-72 and Rashmi were suited for favourable environments. The genotype Megha was found stable for early yield. The F1 hybrids had greater stability for yield across environment compared to open pollinated varieties.
