摘要
The objectives of wheat breeding in Sichuan and Chongqing were incon- sistent with the requirements of wheat production in 1980s. The new direction, to breed new wheat variety with high and stable yield, good quality, resistance to dis- eases, tolerance to spike sprouting, large head, white and big grain and outstanding commercial property, was put out in this article based on the development of wheat production, market economy and the needs of people. Depending on the selection and breeding work of Mianyang Institute of Agricultural Sciences for more than 20 years, new wheat varieties Mianyang 25, Mianyang 26, Mianyang 27, Mianyang 28, Mianyang 31, Xikemai 1 and Xikemai 6 were developed successively, which made a great contribution to the wheat breeding wheat breeding and production in SJchuan and even in China and the national food security.
该研究针对中国西南麦区审定品种与生产实践需要之间的矛盾,从生产发展、市场经济和人民需要出发,分析了当时审定小麦品种较多而推广应用较少的现象,总结了小穗小粒红皮种推广速度慢且农民不愿种植、大穗大粒白皮种推广速度快的原因,并提出了"选育商品型高产优质抗病大穗大粒耐穗发芽白皮小麦新品种"的育种创新工程。经过二十几年的努力,培育出了‘绵阳25’、‘绵阳26’、‘绵阳27’、‘绵阳28’、‘绵阳31号’、‘西科麦1号’、‘西科麦6号’等白皮小麦新品种,这些品种成为了四川省小麦第6次大更换的主要品种,为四川省和中国的小麦育种、小麦生产及国家的粮食安全作出了巨大贡献。
