Abstract:
This study was carried out to assess the nature and magnitude of genotype-environment interaction (GEI) and the correlation among some stability parameters. 15 parents along with 36 hybrids and three standard checks were evaluated in randomized block design with three replications at three locations viz. Udaipur, Banswara and Chittorhgarh region during kharif 2014 at Rajasthan. Combined analysis of variance indicated that the main effect due to location, genotype and genotype by environment interaction were highly significant. Interspecific hybridization is used to improve crops by transferring specific traits, such as yield, improve quality, pest and stress resistance to crops from their wild relatives. When applicable, this approach is a very effective method of gene transfer. Genotype x environment interaction and yield stability was evaluated for total yield per vine for 36 cucumber and snapmelon breeding lines in Rajasthan using the Additive Main Effects and Multiplicative Interaction stability parameter. Genotype x environment interactions showed the inconsistency of the performance of the breeding lines over environments and seasons. The analysis of variance showed that the genotype x environment interaction were significant for total yield.
