Abstract:

G X E interaction and stability analysis carried out in three consecutive years at Maize Research Station, S. D. Agricultural University, Bhiloda to evaluate 51 different land races of maize. The analysis of variance for stability showed that mean squares due to environments were statistically significant for all the traits except grain yield indicating that variability among environments was large enough for a proper estimation of 'b' values. The G x E interaction was significant for four traits viz., plant height, ear height, cob weight and shelling percentage. The stability parameters for plant height showed that LR-09 was stable over the environments while, land races LR-24 and LR-51 were top among all land races for stability parameter for ear height. The land race LR-50 was ideally stable for Cob weight per plot as it exposed higher mean (2.08), near unit regression coefficient (bi=1.17) and non-significant deviation of regression coefficient from zero (s2di= -0.047). In case of shelling (%) land races LR-48 and LR-12 registered maximum shelling percentage and fulfill other parameter (bi and S2di values) of stability.
