GenotypexEnvironment Interaction and Stability for Yield and Its Components in Hybrid Rice Cultivars (Oryza sativa L.)

Abstract

The present investigation was conducted to evaluate 60 hybrid rice cultivars, their parents involving five cytoplasmic male sterile lines and 12 restorer lines along with five checks for their stability across three different agro-climatic zones in Andhra Pradesh, India during kharif 2009. Substansial portion of genotype x environment interaction was significant due to the linear component for panicle weight, number of productive tillers per plant, number of filled grains per panicle, 1000-grain weight and single plant yield indicated significant variability among the experimentation could be predicted.....
