摘要
70年代后期以来,我所先后育成了绵阳11号等6个小麦品种,它们均是70-5858×繁六、繁六×406两个组合的系选后代。绵阳系列小麦品种均属于穗重型,每亩有效穗24～26万,每穗40～50粒,千粒重40～50克,亩产400～450公斤,株高80～90厘米,成熟早,高抗条锈病,蛋白质含量13.62～16.46％,湿面筋含量27.10～32.38％,适应性广泛。从1981～1988年以来,省内外累计推广面积达17000多万亩,以四川省的栽培面积最大,占小麦栽培面积的89.96％,累计增产小麦8589.875万吨,增加产值39.5亿元,纯收益达38.29亿元。根据四川生态气候的特点制定出正确的育种目标是育成绵阳系列小麦品种的基础。在大量搜集小麦品种资源的前提下,采用杂交育种和系统选择的方法是提高育种成效的捷径。通过超前测产,加速繁殖与试验示范相结合,保证了在短期内育成6个小麦新品种。本文首次报道了绵阳系列小麦品种选育的基本经验和育种体会。
Six new cultivars of wheat (Triticum L.), such as Mianyang 11, have been selected succesively since the end of 1970s. They were selected from the hybrids of 70-5858/Fan 6 or Fan 6 /404. They belong to the ecotype with weighty spikes. There were 359.8-389.8 spikes on per square metre and their 1000-grain weights were 40-50 gram. Their yields have usually reached 6000-6750 kg on per ha.. Their plant heights were 80-90 cm. They are early ripening and highly resistant to the stripe rust. Their protein contents were 27.1-32.38%. They could be planted widely in China, The planted area of these cultivars amounted to 11.3 million ha. during 1981-1988. In Sichuan province, the planted area with these cultivars accounted for 89.96% of the overall planted area of wheat and they are still the primary cultivars at present in the province.
