Additive Main Effects and Multiplicative Interactions Analysis of Plant Height in Basmati Rice
DOI:10.30954/0974-1712.12.2018.1
Abstract:
Thirty six basmati rice genotypes were evaluated under four production systems viz. Transplanted rice (TPR), System of rice intensification (SRI), Chemical free cultivation (CFC) and Wet direct seeded rice (Wet DSR) at RRS, Kaul, and RRS, Uchani (Karnal), CCS HAU, Hisar, Haryana during Kharif season of 2016 and 2017. The experiment was conducted using Randomized Complete Block Design with three replications. Yield stability and adaptability of plant height were analyzed by Eberhart and Russell’s and additive main effects and multiplicative interaction (AMMI) model. The environment, genotype main effects, and the GEI were all highly significant. The study indicated that the tested genotypes, such as Pusa 1734-8-3-85, SJR-70-3-2, PAU 6297-1, Pusa 1656-10-705, Pusa 1884-3-9-175, and Pusa-1884-9-12-14 had dwarf plant height, which indicated these genotypes adapted to favorable environments. Based on AMMI biplot analysis, the genotypes, Improved Pusa Basmati 1 and HUBR-16 with low mean and IPCA1 score close to zero, were identified as stable genotype and had general adaptation to all the environments.
