| Abstract: | A new early-maturing rice variety,Zaoxian 807,bred by pedigree method,was characterized by high yielding and resistance to diseases.In Anhui provincial regional plot tests from 2009-2010,its average yield was 7 699.5 kg/hm2,which was 8.25% higher than that of check variety,Zhuqing.In Anhui provincial production trial of 2011,it yielded 6 814.5 kg/hm2 which was 1.66% higher over Zhuqing.It was also characterized by moderate resistance to rice blast and bacteria leaf blight,and tolerance to low temperature at seedling stage.Its grain quality met the fourth-third grade of quality rice standard issued by Ministry of Agricultural of China.The whole growth period is about 108 d,the suitable period is from last ten-day of Mar.to first ten-day of Apr.. |
