利用遗传突变基因改良特用玉米——紫(黑)糯玉米育种与市场开拓的探讨

Application Genetic Mutant Gene for Improvement of Particular Kind Maize—— An exploratory on the breeding and opening up the market of purple(black)glutinous maize

紫(黑)糯玉米问世倍受青睐。但欲育成青穗用与淀粉用的丰产的杂种,难以近期实现。其因是受转座子遗传效应和环境的影响。文中择要介绍了紫(黑)糯玉米的各殊育种途径,制种要点,并对市场开拓各色品种寄予瞻望。同时,还引用“阈值”(ThresholdValue)与“潜默知识”(TacitKnowledge)二词,阐明育种工作的问题,以引起育种者与农业生物技术研究者们的关注。

Purple(black)glutinous maize has soon been bred out and is twice as much favour.But the higher yield hybrids used for premilk stage ears and employes of starch both are hard in near future,owing to the effects of transposon element and environment.This paper showed the looking forward to new type variety and the breeding-method of purple(black)glutinous maize.Simultaneously,it is suggested that the two words i.e.“threshold value”and“tacit knowledge”which were for the question of plant breeding described.In practise,it can be used a project worthly of research for breeders and biotechnology workers.
