Introduction to the Rice Variety Boyou Gan 28
[Basic Information] Boyou Gan 28 (Boyou 752) is a medium-late, late-maturing combination bred by the Rice Research Institute of the Jiangxi Academy of Agricultural Sciences by crossing the male-sterile line Bo A with the self-selected restorer line 752. In spring in Hainan, test crosses were made using the Guangxi male-sterile line Bo A with the strong restorer line 752 (selected from 26 Zhai Zao/BG910) bred by this research group; in the autumn of the same year, a heterosis comparison trial was conducted in the institute's experimental field. The result was outstanding yield, with a measured yield of 102 t/hm2, 9.9% higher than Shanyou 63. Boyou Gan 28 1

Introduction to the Bo II You 15 Rice Variety
[Basic Situation] The Bo (Bo II) You series hybrid rice combinations are the mainstay combinations for late rice in Guangdong, Guangxi and Hainan provinces (regions). However, after years of cultivation, combinations such as Bo You 903 and Bo You 3550 have shown problems such as declining yield potential and weakened disease resistance, causing a marked decrease in planting area. In the early season of 1996, the male-sterile line Bo II A, bred by the Agricultural Science Institute of Bobai County, Guangxi, was crossed with our newly selected high-quality restorer line HR15 (Aihuangzhan x Qingliuai No. 1) to form the combination, producing Bo II You 15,
