Stability analysis of fruit yield and related traits in Ridge Gourd

Abstract

The investigation was carried out to study stability parameters on eight quantitative traits of ridge gourd.  The result showed significant genotypic mean square for most of the characters viz., days to opening of first female  flower, number of node at which first female flower appeared, days to first fruit harvest, number of fruits per vine and  total fruit yield per vine indicating enough variability among the 8 parents and their 28 F 's. The mean square due to 1 environments were highly significant for all the characters (except fruit length), suggesting the existence of  considerable variation among genotypes, as well as environments. The G x E interaction when tested against polled  error was found significant for number of secondary branches per vine. The mean square due to environment (E) +  genotype (G) interaction was obtained significant for days to opening of first female flower, number of fruits per vine  and fruit yield per vine. Joint consideration of means performance and stability parameters revealed that cross  AHRG-1 x Salumber Long had exhibiting below average stability hence, that cross was suited for better  environment.
