利用全基因组育种技术选育紫黑色京山桥米新品系
Breeding of a new purple-black Jingshan Qiaomi rice line using genome-wide breeding technology
摘要
Abstract
To overcome the industrial bottleneck of"high quality but low priceˮ of traditional white-grained Jingshan Qiaomi,enrich varietal types and enhance industrial added value,a rapid breeding system was established within a full-growth-period intelligent breeding facility.Using Yangxizao as the recipient parent and Yunnan local rice variety Yunzi No.1 as the donor parent,a breeding strategy involving"one cross,two backcrosses,and three self-crosses"was implemented.This approach was combined with precise screening techniques using gene chips and phenotypic selection,successfully developing a new purple-black-grained Jingshan Qiao-mi rice line,named Purple-black Yangxizao.The results showed that the new line retained the core agronomic traits of Yangxizao,in-cluding plant type,growth period,and other key characteristics,while achieving the specific improvement of purple-black brown rice.This provided high-quality germplasm resources for the functional and distinctive development of the Jingshan Qiaomi industry.关键词
