摘要: 以5个籼型光温敏核不育系为材料,分别对其柱头外露率、柱头长度、柱头宽度、柱头面积和柱头体积以及柱头活力等指标进行了观察测定,并以柱头外露率作为首要指标进行排序,得出了参试光温敏核不育系材料柱头综合性状表现结果,依次为F168S、信矮10-4S、矮青34S、广占63-4S、信丰9826S。

Abstract: In order to investigate and contrast the stigma characters of indica PTGMS Lines, using 5 indica PTGMS as materials, we observed and measured the exposure rate of stigma, stigma length, stigma width, stigma size, stigma volume and stigma vigor. The results showed that the stigma characters performance of F168S was best, then followed by Xinai10-4S, Aiqing 34S, Guangzhan 63-4S, Xinfeng 9826S, based on the exposure rate of stigma as the primary index.

Key words: indica PTGMS line, the exposure rate of stigma, stigma size, stigma volume, stigma vigor
