Study on Yield Stability of Wheat Genotypes under Rainfed Environments in Intermediate Zone of J&K

Arvind Kumar Singh, SB Singh

Abstract

Sixteen wheat genotypes were evaluated to study the stability of yield and its components by growing them during rabi season for three years from 2006 to 2009 at Regional Agricultural Research Station, Rajouri, J&K. Significant mean square due to genotypes revealed the presence of wide variability among the genotypes for all the traits studied. The component of genotypes x environments interaction was observed significant for all the characters except spike length, effective tillers/plant and biological yield. Based on stability parameters, genotypes UP 2964, HPW 230 and VL 895 exhibited higher mean grain yield and least deviation from zero indicating wide stability for yield. These varieties could be recommended for commercial cultivation for this region.
