与玉米T型雄性不育细胞质连锁的玉米小斑病〔Helminthosporium maydis〕给美国玉米带造成的惨重损失,揭示出单一细胞质的遗传脆弱性,促使人们去寻找新型雄性不育细胞质并期望细胞质的遗传多样性能对作物的抗病性做出贡献.目前已发现高粱有一种正常细胞质,即B细胞质,和四种雄性不育细胞质.源于迈罗的雄性不育细胞质称为A_1细胞质,源于IS12662C的称为A_2细胞质,源于Nilwa(IS1112C)的称为A_3细胞质,源于Kafir的称为A_4细胞质.
Helminthosporium maydis, which is linked to T-type male sterility cytoplasm in maize, caused heavy losses to the corn belt in the United States, revealed the genetic vulnerability of a single cytoplasm, and prompted people to search for new types of male-sterile cytoplasm and to expect cytoplasmic genetic Diversity can contribute to crop disease resistance has now been found in sorghum has a normal cytoplasm, the B cytoplasm, and four kinds of male sterile cytoplasm Male-derived male sterile cytoplasm known as A_1 cytoplasm derived from IS12662C Called A_2 cytoplasm, derived from Nilwa (IS1112C) as A_3 cytoplasm and derived from Kafir as A_4 cytoplasm.
