Progress in Construction and Application of Near-isogenic Line in Wheat
摘要
Abstract
[Objective] The aim was to summarize the construction methods of wheat near-isogenic line and its application progress,to providereference for rational use of near-isogenic line. [ Methods] Several methods used in the coastruction of wheat near-isogenic line were introduced,such as transferring genes in several consecutive backcross generations, segregation genes in mutants and in several consecutive inbred generationsof the hybrid plant on the target site. Moreover,the application of near-isogenic line in multiline varieties cultivation,the mechanism research ofdisease resistance and the bases research of quality foundation were depicted, what's more, the application prospect of it was forecasted. [Result]Near-isogenic line is the ideal material for studying single gene effect, cloning target genes, accurately positioning genes and marker-assistedbreeding,with the continuous nurture of different characters of wheat near-isogenic line,near-isogenic line will be used widely. [Conclusion] Thestudy provides reference for constructing wheat near-isogenic line and its further rational using.关键词
