Agronomic traits
'W25' was similar to '2177s' in investigated agronomic traits such as plant height, panicle length, seed setting and yield potential. Meanwhile, it also had the same combining ability as the parent '2177s', which indicates that 'W25' basically retained the yield potential of F, hybrids produced from '2177s'. Investigation on the dynamics of pollen fertility conversion showed that 'W25' maintained the TGMS characteristics like '2177s'. Its spikelet fertility was mainly controlled by temperature.
