河北省冬小麦品种现状分析

Analysis of Wheat Variety Status in Hebei Province

为了探明河北省冬小麦品种的现状,为小麦育种、栽培和生产服务,以河北省2003-2008年审定的冬小麦品种为材料,分析其植株性状、产量性状和品质状况。结果表明,审定品种幼苗以半匍匐型为主,半冬性品种多于冬性品种,平均生育期242 d左右,白粒品种占98.51%,硬质品种占86.57%,平均产量466.6 kg/666.7 m2,平均株高74.62 cm,穗粒数32.64粒,千粒重39.3 g,容重784 g/L左右,籽粒蛋白质含量14%左右。

The aim of this study was to identify the characteristics of winter wheat varieties in Hebei province in order to improve the technology of wheat breeding,cultivation and production.The winter wheat varieties examined from 2003 to 2008 in Hebei province were used to analyze the characteristics of wheat plant,yield and quality.The results are as follows,the young seedlings of wheat varieties were mainly half-prostrate,and half-winter varieties were more than winter varieties.The average growth period was about 242 days.The white grain varieties accounted for 98.51% of the total varieties,while the hard varieties accounted for 86.57%.The average yield was 466.6 kg/666.7 m2.The average plant height was 74.62 cm.The average kernel number per spike was 32.64.The average weight per thousand grains was 39.3 g.The average test weight was around 784 g/L.The average grain protein content was about 14%.This could provide useful information for the study of high-yield wheat breeding,cultivation and production.
