 ABSTRACT

The investigation was carried out for   characterization of 119 rice Temperature Sensitive Genic Male Sterile (TGMS) lines for morphological, yield traits at fertility favoring environment; sterility and floral traits at sterility favoring environment. The analysis of variances exhibited highly significant differences for all the character studied except sterile lemma length. The TGMS lines viz., TNAU 115S and TNAU 139S was found to be earlier for days to 50% flowering in both environments. Based on floral traits viz., pollen fertility per cent, pollen sterility per cent, panicle exertion per cent, anther length, stigma breadth, glume opening angle, the following TGMS lines namely TNAU 147S, TNAU 103S, TNAU 14S, TNAU 19S, TNAU 45S  and  TNAU 100S were identified as promising TGMS lines. These lines can be used as male sterile parents for development of two line rice hybrids.

Keywords: Characterization, Rice, TGMS, Morphological, Floral traits.
