摘要: 从水稻育种材料后代中获得1个受隐性单基因控制的簇生穗突变体(Cl-dz)。其表型特征为:在二次枝梗顶端有2~3个小穗簇生在一起,呈"W"形态。遗传分析表明该性状是受单基因控制的隐性性状。利用突变体Cl-dz与保持系冈46杂交构建F2定位群体,将该基因定位在6号染色体的SSR标记RM6036与RM1340之间,遗传距离分别为3.6cM和7.0cM。

Abstract: A clustered spikelets mutant(Cl-dz) controlled by single recessive gene was found in the progeny of a rice breeding material, its phenotype characteristic was that 2 or 3 spikelets cluster on the second stem in the shape of "W". Genetic analysis indicated that the trait was a recessive trait genetically controlled by single gene. The F2 mapping population was constructed by hybridization between mutant Cl-dz and G46. And the gene Cl-dz was mapped between SSR markers, RM6036 and RM1340 in chromosome 6 of rice. The genetic distance was 3.6 cM and 7.0 cM, respectively.
