Abstract

Evaluating Amaranthus genotypes is a key task for Amaranthus improvement programs. Generally, the genotypes that were found as being steady and high yielding are often recommended for cultivation at the farmer level. For this purpose, 20 Amaranthus genotypes were subjected to stability analysis to determine the nature and extent of genetic stability for across locations, village Pakh, Ghansali, Tehri Garhwal district for grain yield and yield components. A randomized complete block design (RCBD) was used in this study with three replications for the identification of stable and high yielding genotypes. The results showed that genotype probability level of 0.05 significantly influenced the grain yields of Amaranthus genotypes. Genotypes IC-340943 (43.03g) and IC-317517 (39.49g) with more than unity regression indicated the genotype’s suitability for favorable conditions. GenotypeIC-340943 was stable among all the genotypes. Thus, to improve the production of Amaranthus in the hills of Uttarakhand, the genotypeIC-340943 were put forward for release as a variety.
