Study of specificity in adaptability of rice (Oryza sativa L.) genotypes to specific environment
Abstract
A field experiment was conducted in Randomized Block Design with three replications at three locations viz., Educational and Research Farm, Department of Agricultural Botany, College of Agriculture, Dapoli, Agricultural Research Station, Shirgoan Dist. Ratnagiri and Agricultural Research Station, Phondaghat during Kharif 2016. The AMMI model, which combines the standard analysis of variance with IPC analysis was used to investigate G × E interaction. In AMMI model, the contribution of each genotype and each environment to the GEI is assessed by the use of biplot graph display in which yield means are plotted against the scores of the IPCA 1. In interaction principle axis of AMMI biplot, first interaction principle axis (IPCA I) were favorable for all the characters but the second interaction principle axis (IPCA II) were favorable for characters such as spikelets fertility, grain yield plot-1 (kg), the number of panicles square meter-1, protein content (%), iron content (ppm), amylose content (%), grain yield plant-1(g) and total number of spikelets panicle-1. The genotype viz., RTN-1201-13-2-2-1-32 was found most favourable for all the characters in the entire three environments with high yield, maximum plant height and more content of micronutrients. The genotype viz., RTN1211-4-2-1-1 was found stable for grain yield plot-1, grain yield plant-1 and protein content. The genotypes RTN-1201- 51-2-1-5-48, RTN-1211-5-1-3-5 and RTN-1201-5-1-3-14 were found to be stable for Dapoli and Shirgaon locations for the traits viz., grain yield plant-1, grain yield plot-1 and micronutrients. The genotypes viz., RTN-1201-51-2-1-5-48 and RTN-1211-6-1-3-1-8 were found stable for Shirgaon location for traits viz., spikelet fertility, test weight, plant height,
panicle length and micronutrients
