马铃薯2n配子遗传机理及其在育种中的利用价值

本文以反映国内外马铃薯2n配子研究利用动态的大量文献为基础,综述了马铃薯2n配子在物种上的分布和细胞遗传学基础,并着重阐述了马铃薯2n花粉的形成机制、类型及其遗传效应.对2n配子在马铃薯杂种优势利用、实生种子选育、传递主效显性基因的作用和综合转移野生种有利基因方面的利用价值作了详尽的论述,并分析了2n配子研究利用的发展趋势.

Genetic Mechanisms of Potato 2n gamete and Its Utility Value in Breeding

Based on a vast amount of data that reflected the development on research and use of 2 n gamete at home and abroad, this paper summarized the distribution of 2 n gamete in potato species, the basis of cytogenetics, and expounded emphatically the mechanisms of 2 n pollen formation, the types on 2n pollen and its genetic effect.Made an exhaustive discussion of the use value of 2 n gamete in the use of potato heterosis; breeding of ture potato seed; the affect transmited dominant gene and the affect synthesized and transfered the beneficial gene in wild resources. And analyzed the development tendency of the research and use of 2 n gemete.
