1989年8月8日至9日,四川省农科院邀请了省内外专家17人,组成评审组,对四川水稻高梁所的水稻光敏核不育系选育和两系法杂交配组进行了现场参观和评议,主要是通过田间检查和室内镜检,对三个光敏核不育材料进行了评审,其结果如下:LW1S:群体1300株。田间目测不育株率100％,套袋不育度为100％。随机取样镜检114株,其中105株为典园败株,9株有少量正常花粉,最高正常花粉率8％。农艺性状完全稳定。 From August 8 to August 8, 1989, Sichuan Academy of Agricultural Sciences invited 17 experts from both inside and outside the province to form a review group to carry out the screening and the two-line hybrid rice breeding of Sichuan rice sorghum The site visits and comments, mainly through the field inspection and indoor microscopy, the three photosensitive nuclear sterile materials were reviewed, the results are as follows: LW1S: 1300 population. In the field, the rate of infertile plants was 100%, and the sterile value of bagging was 100%. A total of 114 samples were screened by random sampling, of which 105 were typical dwarf plants, 9 had a small amount of normal pollen and the highest normal pollen percentage was 8%. Agronomic traits completely stable.
