Yield and stability analysis of some sesame (Sesamum indicum) genotypes in Turkey

Abstract

This study was carried out during 2015 and 2016, using 16 sesame (Sesamum indicum L.) genotypes (Golmarmara, Boydak, Sarisu, Tanas, Muganli-57, Cumhuriyet 99,Osmanli 99, Tan 99, Kepsut 99, Hatipoglu, Aslanbey, Baydar 2001, Batem Aksu, Ozberk-82, Orhangazi 99 and local line Pakistan), evaluated for stability characteristics of the genotypes examined through seed yield. Seed yield averages, regression coefficients (bi), deviations from regression (S(2)d), regression line intercept values (a) and determination coefficient values (r(2)) of genotypes were examined as stability parameters Minimum and maximum values of examined criteria included seed yields between 1035 and 1989 kg ha(-1), regression coefficients between 0.79 and 2.53, deviations from regression between 9.71 and 773.36 intercept values between -211.227 and 271.802, and coefficients of genotypes between 0.002 and 0.945. The cv. Boydak was the most suitable values in terms of stability criteria.
