中绿１号绿豆种子于１９９４年经返回式卫星搭载后，经过３年的地面种植和筛选得到了基本稳定的长荚型突变系，该突变系荚长１６ｃｍ左右，每荚种子粒数为１５～１９粒。通过对３个形态和荚长都基本稳定的突变系和原始对照品系之间的ＲＡＰＤ分析，从１００个１０－ｍｅｒＯｐｅｒｏｎ引物中筛选出３个能产生稳定的遗传多态性的引物，其特异扩增产物分子量依次为１．４ｋｂ、１ｋｂ、２ｋｂ，因此分别命名为ＯＰＺ－１３１４００、ＯＰＹ－０７１０００、ＯＰＹ－０４２０００。ＯＰＺ－１３１４００和ＯＰＹ－０７１０００的克隆和鉴定工作已经完成，其中ＯＰＹ－０７１０００转换成了稳定的ＳＣＡＲ标记。３个突变系进行ＲＡＰＤ分析，彼此之间没有发现扩增产物的差异，它们与原始对照之间却有着共同的差异，表明长荚型突变品系在ＤＮＡ分子水平上已接近同源。
After the green mung bean No. 1 was carried by a return satellite in 1994, a basically stable long-pod mutant line was obtained after three years of ground planting and screening. The mutation was about 16 cm in length and 15 ~ 19 tablets. Three RAPD analysis of 100 10-merOperon primers were used to screen for stable genetic polymorphism by RAPD analysis between three mutant lines with basically stable morphological and pod length and the original control lines. The molecular weight of the products increased 1.4kb, 1kb, 2kb, so named OPZ-131400, OPY-071000, OPY-042000. Cloning and characterization of OPZ-131400 and OPY-071000 has been completed, with OPY-071000 converting to a stable SCAR marker. The three mutants were analyzed by RAPD, and no difference was found between them. There was a common difference between the three mutants and the original one, which indicated that the pod mutants were nearly homologous at the DNA molecular level.
