STABILITY ANALYSIS OF SOME SOYBEAN GENOTYPES USING PARAMETRIC AND NONPARAMETRIC METHODS IN MULTI-ENVIRONMENTS

Seed yields of 14 soybean genotypes were evaluated in four locations i.e. Adana, Şanlıurfa, Antalya and İzmir under second crop conditions through summer seasons from 2014 to 2016. The aims research are estimate the stability parameters terms seed yield by used different analysis methods across eleven environmental study interrelationship among these methods. variance for revealed that environments as well genotype x environment interactions (GEI) statistically significant at P<0.01. Environmental effects contributed 51.04% total sum squares whereas GEI 20.8% 2.59%, respectively. According most methods, BATEM 223, 306, 317 KASM 02 determined be stable genotypes. These demonstrated superior adaptability with high performances many environments. Results correlation indicated was positively significantly correlated Di2 (P<0.01), Si(6) (P<0.05) TOP (P<0.01) showed a negative Pi RS (P<0.01). In addition, coefficient regression (bi) had associated CVi, αi Ri2 (P<0.05).
