Abstract:
Stability analysis in red amaranths (Amaranthus tricolor L.) on twenty genotypes evaluated in four environment years 2017-18, 2018-19, 2019-20 and 2020-21 at Pt KLS College of Horticulture and Research Station, Rajnandgaon, Chhattisgarh. Analysis of variance indicated significant variation between genotypes for all traits except the studied plant height, leaf width and petiole length. The pooled analysis of variance indicated significant variation among the environments for all the characters studied revealed that the environments were random and different and they exercised influence on the expression of characters. Analysis of variance revealed that both linear and non-linear components of genotypes environment interaction (GEI) was found to be non-significant for all characters. This indicated that the genotypes performed uniformly in different environments means genotypes having almost similar values in four environments. When the genotypes were grouped according to Eberhart and Russell stability model, it was concluded that genotypes namely, Amar-09, Amar-03, Amar-07, Amar-15 Amar-12, Amar-21, Amar-23 (Pusa Lal Chaulai), Amar-20, Amar-08, Amar-17, Amar-11 were most stable and well adopted to all four environment conditions for the all study characters.
