选用综合农艺性状好、配合力高，但抗病性和品质较差的高粱恢复系晋粱５号为改良对象，通过组织培养获得高粱体细胞无性变异系Ｒ１１１，田间鉴定和室内化验分析表明，Ｒ１１１比原亲本材料抗丝黑穗病、抗倒、耐旱、耐瘠，品质等性状明显提高。同现有几个主干不育系测配后，选育出一个新的杂交种。试验表明，通过组织培养，选育优良的无性变异系，是创造新的种质资源的有效方法。这种方法不仅可以保持原亲本材料的优点，而且可以改良其不利性状 Selection of sorghum restorer line Jinliang 5 with good agronomic characters and high combining ability but poor disease resistance and quality was used to obtain sorghum somaclonal variation line R111 by tissue culture analysis. R111 was more resistant to head smut than the original parent material, and the traits such as resistance to drought, drought, barrenness and quality were significantly improved. After mating with several existing CMS lines, a new hybrid was bred. Experiments show that through tissue culture, breeding asexual clonal lines, is to create new germplasm resources, an effective method. This method not only retains the advantages of the original parent material but also improves its unfavorable traits
