Progress of Study on Crop Mutation Breeding
摘要
Abstract
Exploitation of natural and induced genetic diversity is the basic requirement of plant breeding in developing plant varieties for sustainable food production.With the shortage of crop cultivated gene pool,mutation breeding technol-ogy has become an important way for the germplasm innovation and digging new genes.This paper reviews the develop-ment history of plant mutation breeding,the main characteristics,similarities and differences of physical mutagenesis and chemical mutagenesis,as well as its application in agriculture breeding.Since the main problem of mutation breed-ing is still lower beneficial mutation frequency,the direction and nature of the mutation is hard to control,Thus,increas-ing the efficiency of mutagenesis,rapid identification and screening of mutants as well as to explore ways for directed mu-tagenesis is an important future perspective for research subject.关键词
