Evaluation of Agronomic Traits and Thermo-sensitive Gene(s) of Some TGMS lines

Abstract

      Two-line hybrid rice has been developing in Vietnam. By 2013, 11 two-line hybrid varieties have been recognized as national varieties. This study aimed to characterize agronomic traits, yield characters and tms genotypes of TGMS lines. In spring season 2013, the TGMS lines showed following performances: 140-163 days growth duration, 14-16 leaves, 62.2-84.6cm in plant height, 19.5-25.8 cm in panicle length, short flag leaf, incomplete panicle exsertion, compact architecture, high rate of long filament, long flowering duration (4-10 days), 168.8-208.8 seed per panicle and, 19.3-26.2 gram in 1000 seed weight. All 16 TGMS lines were genotyped with tms5 while 827S line had both tms4 and tms5 gene.
