MULTI-ENVIRONMENT TRIAL ANALYSIS BY PARAMETRIC AND NON-PARAMETRIC STABILITY PARAMETERS FOR SEED YIELD IN WINTER RAPESEED (Brassica napus L.) GENOTYPES

The objective of this study was to determine the stability 11 different rapeseed genotypes in terms seed yield, throughout 3 years (2014-2015-2016), locations (Tekirdag, Kırklareli, Edirne), total 8 environment Thrace Region. experiment designed as a randomized complete block design with four replications. aim having high adaptation for yield. Parametric (Wi2, bi, Sdi2, Bi, σi2, ri2, Sxi2, CVi and Pi ) non-parametric (Si(2), Si(3), Si(6), RS TOP) statistics were used genotypes. analysis variance yield showed that genotypes, environments genotype by interaction all significant (P˂0,01). According parametric (except TOP methods) analysis, Wosry 142 determined well-adapted genotype; 144 poorly adapted across environments. Genotype may be recommended cultivation tested.
