| Abstract: | To hybrid Minghui 63 of strong restore ability and high combining ability as female parent and Yunnan soft rice Dianlong 201 as male parent,the scent soft rice restore Wenhu 206 with qing scent,strong restore ability,high combining ability,disease resistance and high adaptability is selected.According to the method of high quality and high quality combining,scent and scent combining,the crosses between Wenhu 206 and scent CMS line Yixiang 1A,Wenfu 7,A new scent soft rice combination is selected.It possess the characteristics that grain quality was up to the state standards of the one class fine quality rice,seeds and seedling with concentrated scent,grain scent is fairer far than its parents,high yield,disease resistance,high adaptability,the cooking and eating quality was up to scent,soft and embellish,and to get high quality and high yield in many provinces trial and demonstration.Besides,to discuss the methods and pathways for building the hybridize parents of excellent quality by Yunnan scent soft rice germplasms and for selection breeding the hybrid rice of high quality,to discuss the scent gene genetic expression of Yunnan rice germplasms and the problem of breeding application. |
