重庆市“九五”联合育种攻关项目——两系法小麦杂种优势利用,取得重大突破。这项技术为改变我国南稻北麦格局和使杂交小麦大规模走向生产创造了重要条件。这个项目是针对南方常规小麦产量低、品质差而确定的。今年下半年,7个表现出较强杂交优势的新组合可小面积试制并进入小区鉴定。上年度提供的4个两系法杂交小麦组合去年进入区试,表现仍然稳定,其 Chongqing City, “95” joint breeding project - two lines of wheat heterosis utilization, made major breakthroughs. This technology has created important conditions for changing the pattern of rice in South China and North China and for making large-scale hybrid wheat production. This project is for the South conventional wheat production is low, poor quality and identified. In the second half of this year, seven new combinations that demonstrated strong hybridization advantages could be pilot-sized and entered the community. Last year, four combinations of two-line hybrid wheat to enter the district test, the performance is still stable, its
