稻属有 2 2个种 ,包括 2 0个野生稻种和 2个栽培稻种 ,现已命名AA、BB、CC、BBCC、CCDD、EE、FF、GG和HHJJ9个基因组。野生稻是一个重要的有利基因库 ,包含对各种生物胁迫的抗性和非生物胁迫的耐性基因。就野生稻的有利性状、野生稻有利基因转移研究进展作了概述 ,并对野生稻有利基因分子标记定位研究 ,野生稻有利基因转移的遗传机制以及野生稻有利基因利用前景进行了讨论 There are 22 species of Oryza, including 20 wild and 2 cultivated Oryza species, now named as AA, BB, CC, BBCC, CCDD, EE, FF, GG and HHJJ9 genomes. Oryza officinalis is an important favorable gene pool, which contains resistance genes to various biotic stresses and abiotic stresses. This paper summarized the favorable traits of wild rice and the research progress of favorable gene transfer in wild rice, and discussed the molecular marker localization of wild rice, the genetic mechanism of favorable gene transfer in wild rice and the prospect of favorable gene utilization in wild rice
