小麦品种资源农艺性状鉴定与评价

Evaluation and Identification on Agronomic Characters in Wheat Germplasm Resources

通过对1 692份小麦品种资源农艺性状进行调查、鉴定与评价,结果表明:株高、穗长、穗粒数和千粒重的变异系数均大于14.7%,在综合鉴定和评价的基础上,筛选出早熟品种195份、矮秆品种66份、大穗品种36份、多粒品种22份和大粒品种44份。

In this paper, the experiment was layed out with 1692 wheat varieties which were provided by Institute of Crop Germplam Resources of Xinjiang Academy of Agricultural Sciences. Its agronomice characters were investigated, The result din-frustrated that the coefficients of variability of plant height, spike length, kernels per spike and 1000 - grain weight were all beyond 14.7 % ; some elite wheat resources of desirable characters were selected, including 195 resources with early- maturity, 66 resources with short - height, 36 resources with big spike, 22 resources with much - kernel per spike and 44 resources with big grain.
