Genotype and environment interaction analysis for quality traits in Basmati rice

Kesh, Hari ; Battan, Khushi Ram; Kumar, Deepesh ; Kaushik, Prashant


A total of 36 rice genotypes including traditional varieties, evolved varieties and some advanced materials were tested for physical and biochemical quality parameters. Experiments were conducted at two locations with four resource-saving environments and two consecutive years in a randomised block designs. Multi-environmental data was analysed using additive main effect and multiplicative interaction (AMMI) and genotype and genotype × environment (GGE) interaction model for quality parameters. Genotype × environment interactions (GEI) were noticed significant for all the studied parameters excluding alkali spreading value, grain breadth before and after cooking and grain length after cooing. Hulling, milling & head rice recovery were observed maximum in transplanted and system of rice intensification production system. Among production systems, SRI recorded a high mean value for all the traits followed by transplanted rice, chemical free cultivation and direct seeded rice. Improved Pusa Basmati 1, Pusa Basmati 1121, Pusa 1884-3-9-175 and SJR-70-3-2 were observed as stable genotypes across the environment coupled with the high mean for amylose content.
