Abstract:

Stable performance of Thermo-sensitive Genic Male Sterile lines (TGMS) for pollen and spikelet sterility is critical for hybrid seed production in two –line hybrids of rice. The objective of this study is to investigate nine traits in twenty five TGMS lines across three locations viz., Coimbatore (E1), Aduthurai (E2) and Ambasamudram (E3). GGE biplot method was used to analyse the multi-environment data. There was a significant interaction between genotypes and environments for focused traits viz., pollen and spikelet sterility. Among the two weather parameters studied, temperature was found to be the major determinant for sterility induction besides genotypic background. The TGMS lines viz., TNAU 14S, TNAU 100S, TNAU 101S, TNAU 116S, TNAU 124S, TNAU 135S, TNAU 18S, TNAU 139S, TNAU 143S, TNAU 147S, TNAU 151S, TNAU 45S, TNAU 46S and TNAU 67S were best performing and stable genotypes in terms of pollen and spikelet sterility%. Apart from these traits, TNAU 151S and TNAU 124S were found to be stable and best performing for productive tillers, TNAU 139S for panicle exsertion %, TNAU 45S for angle of glume opening, TNAU 67S for stigma exsertion % and TNAU 46S for stigma exsertion % and panicle length. In the present study, Aduthurai has been identified as a suitable location for production of two line hybrids apart from Coimbatore.
