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

Published on

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
