摘要
[目的]描述四川小麦育种的概况和今后四川小麦育种走向,并为小麦育种和栽培提供一定的帮助。[方法]选定1999～2008年由四川省农业科学院作物研究所选育的19个优质小麦品种进行相关的产量和品质分析。[结果]"川麦号"系列小麦产量多半介于5.0～5.5t/hm2,其有效穗和千粒重变异系数是10.11%和7.91%,在保持原有产量结构的基础上,增加穗数和千粒重是今后提高四川小麦产量的有效途径。从品质分析看,"川麦号"系列小麦中,2个品种达到二等强筋小麦标准,大多数品种筋力属中到弱筋标准,单个指标表现突出,但整体品质偏低;其湿面筋、沉降值以及稳定时间变异丰富,提高潜力很大。[结论]证明了四川地区培育高产优质小麦的可行性。
[ Objective ] The help for the wheat breeding and cultivation was provided through the description of the information and the develop- ment direction of wheat breeding in Sichuan province. [ Method] The relationship between of the Relationship between agronomic traits and quality of 19 good-quality wheat varieties, bred by Crop Research Institute of Sichuan Academy of Agricultural Sciences from 1999 to 2008, was ana- lyzed. [ Results] The yield of most of those wheat varieties was 5.0 - 5.5 t/hm2 ; the variable coefficient of effective panicle and 1 000-seed weight was 10.11% and 7.91%. The efficiency approach of the improvement of wheat yield in Sichuan was to increase the effective panicle and 1 000-seed weight based on the yield structure-maintaining of the wheat. From the view of wheat quality,2 wheat varieties reached to the second - class quality standard of strong gluten wheat and most of wheat varieties were the middle to weak gluten wheat in a serial of wheat varieties- Chuanmai. In all of varieties, there was the character： outstanding single standard and low whole standard. There were the rich variation in the content of wet gluten, the sedimentation value and the stable time and the great potential in the yield improvement. [ Conclusion ] It was proved that it was feasibility to breed high-yielding and good-quality wheat variety in Sichuan.
