摘要
病害、干旱、盐碱等逆境胁迫是棉花生产实现高产稳产的主要影响因素,利用传统育种和现代生物技术对现有棉花育种资源的抗逆性状进行遗传改良是实现高产、优质、多抗育种目标,培育突破性棉花新品种的有效途径。综述了中国农业科学院棉花研究所棉花抗逆遗传改良团队近年来在棉花抗逆育种新材料创制、抗逆育种关键技术研发与新品种培育方面的最新进展,并且提出了未来我国棉花抗逆遗传改良的研究方向。
Abiotic or biotic stress such as disease, drought and salinity is the main influence factors that improving and stabilizing the cotton yields. Genetic improvement for cotton stress resistance using traditional breeding strategy and modern biotechnology can realize the objects of high yield, superior quality and multiresistance and cultivate breakthrough cotton variety in cotton breeding. We reviewed the recent achievements in creating the new cotton lines for stress resistance, developing the key technologies for cotton stress resistance improvement, and cultivating the new cotton varieties, which achieved by the group of genetic improvement for cotton stress resistance in the Institute of Cotton Research of Chinese Academy of Agricultural Sciences. What＇s more, we presented the future scope, the purpose and the prospect of genetic improvement for cotton stress resistance in China.
