中稻两用核不育系0SH089和0SH099的特征特性研究
Characteristics of Medium Rice Male Sterile Line 0SH089 and 0SH099
摘要
Abstract
In this study, several agronomical characteristics and grain quality traits of two newly developed FTGMS lines (0SH089 and 0SH099) were observed, the results snowed that the growing duration from seeding to heading of 0SH089 and 0SH099 was 79 d, shorter than that of C8I5S; The flag leaves of the two new FTCMS lines were long, straight and wide which made them get a higher light use efficiency, 0SHOS9 and 0SH099 characterized with strong tillering ability, compact plant type and strong lodging resistance, the plant height were 64.8 cm and 63. 3 cm respectively. The total number of spikelets were 197. 3 and 196.2, also with high spikelet density features. A long floral opening duration, high non - closed floral rate and high outcrossing rate was found on 0SH089 which was better than OSH099, however, for these features , both of the two new PTGMS lines were better than the control line C815S, indicated a considerable potentials for the seed production yield; The grain quality analysis results showed that both of 0SH089 and 0SH099 were very good and a couple of the quality traits meet the national first grade standards of excellent indica rice varieties.关键词
