Study on Yield Stability of Wheat Genotypes under Rainfed Environments in Intermediate Zone of J&K
Main Article Content
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.
Signifi cant 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 signifi cant 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.
