“川农号”系列小麦产量和抗病性相关分析

Analysis of the Relationship between Agronomic Traits and Disease Resistance of Wheat Varieties-Chuannong

[目的]描述四川小麦育种的概括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1999～2007年由四川农业大学任正隆课题组选育的17个优质小麦品种进行相关的产量和抗病性分析。[结果]"川农号"系列小麦大多属于早中熟春性品种,产量介于5 000～5 500 kg/hm2,增产幅度较为明显,高抗条锈病,中感白粉病,其有效穗和穗粒数变异系数是11.11%和11.47%,在保持原有产量结构的基础上,增加有效穗和穗粒数是今后提高四川小麦产量的有效途径。[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 development direction of wheat breeding in Sichuan province.[Method] The relationship between agronomic traits and disease resistance of 17 good-quality wheat varieties,bred by the Ren zheng-long studying team of Sichuan Agricultural University from 1999 to 2007,was analyzed.[Results] Most of wheat varieties—Chuannong was middle-early maturity and spring variety.The yield of those was 5 000-5 500 kg/hm2.The variable coefficient of effective panicle and grains per spike was 11.11% and 11.47%.The efficiency approach of the improvement of wheat yield in Sichuan was to increase the effective panicle and grains per spike based on maintaining the yield structure of the wheat.[Conclusion] It was proved that it was feasible to breed high-yielding and good-quality wheat variety in Sichuan.
