Abstract:

The genotype and genotype by environment biplot model is a valuable tool for visualization of multi-environment data. In this study, we investigated six traits for eight thermo-sensitive genic male sterile lines in rice across three environments viz., Aduthurai, Ambasamudram and Coimbatore. The first two principal components (IPC1 and IPC2) were used to create a two dimensional GGE biplot. In terms of agronomic performance, the study has identified the lines TNAU 14S (G3) for days to 50% flowering and number of productive tillers; TNAU 45S for plant height and productive tillers; GDR 61S and TNAU 39S for panicle length and GDR 70S, TNAU 95S for plant height and productive tillers respectively. The lines TNAU 45S (G6), TNAU 60S (G7) and TNAU 95S (G8) were stable for pollen sterility% and spikelet sterility%. among all the eight genotypes, TNAU 45S (G6) was identified as the best performing and stable line for pollen and spikelet sterility, more number of productive tillers and desirable height. The study has identified a new location viz., Aduthurai (E1) as the ideal environment for production of two line hybrids in rice apart from Coimbatore (E3).
