G x E interaction and stability analysis of promising rice cultures under different sowing dates during kharif
Abstract
A field experiment was conducted with six advanced Rajendranagar rice cultures along with three popular varieties (BPT 5204, JGL-11470 and MTU-1010) as checks to estimate the stability parameters. The linear part of GxE interactions was significant for plant height, grains per panicle, 1000 grain weight and kernel length. Whereas, non linear part was significant for grain yield, for which prediction of performance is not possible. Higher stability was noticed for grain dimensions in a relative comparison to grain yield and its components, which indicated that the time of planting had less influence on physical grain characters. Considering the three stability parameters RNR 15028 for grain dimensions, RNR 15038 for yield potential and RNR 15048 for grain fineness as well as for yield were identified as promising genotypes in comparison to popular check varieties of the region viz., BPT-5204, JGL 11470 and MTU 1010.
