Evaluation of Genotype –Enviroment Interactions of New Peanut Varieties Conditions of Tra Vinh

Abstract

The experiment comprised of 10 lines were laid out in a randomized block design replicated three times at 6 different locations at Dong Xuan and HeThu season from Tra Vinh . Analysis of variance indicated the presence of significant genetic variability among the genotypes for peanut under all the 6 location. All analysies of variance for the yield of peanut that were pooled over the six locations . Genotypes x Enviroment ( GxE) interactions were also found significant and the mean squares due to environment were highly significant indicating sufficient diversity among the environments. Four lines HATRI 02DP, HATRI 03DP, HATRI 14DP give hight yield both dong xuan and wet season . performed better by in all the locations both satbility at Dong Xuan and HeThu seasones. This varieties is good for multilication in the future .
