| Abstract: | Yu 802A,derived from crossing 1840A to the single plants selected from the F3 generation of YouⅠB/Ⅱ-32B with somatic cell culture,is an indica CMS line in rice,developed by Chongqing Academy of Agricultural Sciences through the successive backcross and selection.With the characteristics of stable male sterility,fine grain quality,good outcrossing habits and high combining ability,it was technically identified by Chongqing Crop Variety Appraisal Committee in August,2007.Some of its hybrids including Yuyou 600(Yu 802A/Yuhui 6003),Yuyou 528(Yu 802A/Yuhui 528),Yuyou 1351(Yu 802A/Yuhui 1351),Yuyou 7109(Yu 802A/Yuhui 7109)and Yuyou Hong 9(Yu 802A/Yuhui 9341)have been certified for release to commercial production by the national or provincial crop variety appraisal committees. |
