Method for mutation breeding the sesame at space environment

Abstract: The invention discloses a method for sesame mutation breeding in the space environment. The method comprises the following steps: firstly, Yuzhi No.4 purified seeds are embarked for space mutation and idiogamy and purification; secondly, the seeds are embarked in a recoverable satellite, and the seeds brought back to the ground are sown in the last ten days of May in the next year; thirdly, single grain spot seeding is performed to the seeds brought back to the ground in a test field, to which leveling and tectorial planting are performed, mulching film is covered, and uncovered after sprouting, single plant harvest is performed during harvest period, and primary parent plants which are not embarked are arranged for comparison; fourthly, from the second generation on, beneficial mutation plant strains are selected, and the primary parent plant breed and the major cultivar in the local production are arranged for comparison; fifthly, for the superior mutant lines in third and fourth generations, identification to traits such as genetic stability, quantity of output, quality, resistance, and adaptability are performed; sixthly, mutant lines with superior comprehensive traits and good prolificacy are selected. In the invention, the new breeds of Zhongzhi No.11 and Zhongzhi No.13 with high yield, high quality, multi-resistance and broad adaptability are bred in a short breeding period, and the breeding period is two to three years shorter than the conventional hybridization and breeding.

Primary Study on Mutation Effect in Taproots of Radish Cultivar "Huangzhou" by Ethylmethylsulfone (EMS)

Abstract: Mutation breeding by Ethylmethylsulfone (EMS) has several advantages: high mutation ratio, many mutated phenotypes and low destruction which has been widely applied for crop breeding. We traced to uncover the mutagenic effect of EMS to Huangzhou radish by ...

Some Biochemical and Biotechnological Perspectives in Wild Chickpea and its Induced Mutants

Abstract: The genus Cicer comprises 9 annual species and 31 perennial species and out of 9 annuals one species is under cultivation namely Cicer arietinum The existing genetic variability has been harnessed in plant breeding programme which further narrowed the genetic base in cultigens Therefore, from the variation enhancement point of view, the present study has been undertaken to assess the mutagenicity of the physical and chemical agents The mutation breeding or mutagenesis is one of the important and useful technique and protocol to increase the mutation spectrum in the wild species which in turn could be introduced into the cultivated species to improve the qualitative and quantitative traits SDS- PAGE electrophoresis is significance tool to assess the variation in the treated materials in form of protein profile The seed protein profile has been studied in wild chickpea and its mutant treated with chemical and physical mutagens separately and in combination treatment and compared with the untreated parent The analysis of the banding pattern of the control and induced mutants has been performed as per UPGMA grouping and Jaccard Similarity Coefficient The maximum major band has been observed in the control while its mutants represent less than that of the control The polypeptide bands shows varying size from 592 KDa to11908 KDa The genetic distance between all the 10 treatment varied from 0333 to 075 as revealed by Jaccard Similarity Coefficient The dendrogram represent one parent and 9 mutants into two major cluster in the present investigation The induced mutants represent the deviation from the parent indicating variation when compared to the control in the present study
