Abstract: Adaptability and AMMI biplot analysis was carried out to identify adaptable and stable genotypes of Basmati rice for non-conventional resource conserving production environments. A set of 36 basmati rice genotypes comprising released varieties and elite lines including was evaluated under four production systems viz, conventional TPR and non-conventional SRI, CFC and DSR (wet). The experiment was conducted during Kharif 2016 and 2017 season in RBD with three replications at experimental farm of College of Agriculture, Kaul and Regional research station, Uchani (Karnal).The Under DSR (wet seeding) pre-germinated seeds after priming for 24 hours were dibbled in puddled soil surface (wet seeding). In general, genotypes responded differently for various traits under different production systems. Pusa Basmati 1121 recorded highest (22%) increase under SRI system over TPR followed by HKR 11-447 (20%) and Pusa Basmati 1 (18%). Pusa Basmati 1, Pusa Basmati 1734-8-3- 85 and Pusa Basmati 1637-2-8-20-5 yielded 8-16 % higher in CFC compared to TPR. CSR 30, PAU 6297-1, HKR 98-476 yielded equal in TPR and DSR. Among production systems SRI was found best followed by TPR, CFC & DSR (wet). The G X E interaction was analysed following two models i) Eberhart and Russel (1966) and ii) AMMI (1988). The mean sum of squares due to genotype x environment interaction were significant for all the traits except grain breadth before cooking, grain length after cooking, grain breadth after cooking, and alkali spreading value. For grain yield per plant, genotypes Pusa Basmati 1121, Pusa Sugandh 3, Pusa Sugandh 6, Improved Pusa Basmati 1, HKR 11-509, SJR-70-3-2, HKR 11-447 and Pusa 1884-3-9-175 were found suitable for better environment whereas, Pusa Basmati 1509, Pusa Sugandh 5, HKR 06-434, Pusa 1826-12-271-4, Pusa 6295-2 and Pusa 1656-10-705 for poor environment. According to AMMI biplot analysis, Pusa Sugandh 3, HKR -11-509, Pusa Sugandh 5, HKR 06-434, Pusa Basmati 1509, Pusa 1734-8-3-85 for grain yield per plant were found suitable for general adaptation to all the environments.
