摘要
１９９２年用稻瘟病菌（Ｐｙｒｉｃｕｌａｒｉａｇｒｉｓｅａ）粗毒素掺入水稻花药培养基中在愈伤组织阶段进行抗性诱导，采用一穗单传选变异法，异地加代，１９９４年在ＤＨ群体四代中获得１３份抗性较好的株系，其中紫米９２１Ｈ农艺性状优良且高抗稻瘟病。
Coarse toxin from pyricularia grisea were mixed with N 6-1 (add 2, 4-D 2 mg/l+6-BA 2 mg/l)media to induce blast resistance through rice anther culture at the callus-inducing period in 1992 We obtained 13 strains bearing good blast resistance at the F 4 of the double haploid(DH) population The purple rice 921 H reaches 7 500 kg/hm 2 with high blast resistance and good quality was finally developed in 1995
