春谷登记品种农艺性状、品质和产量的综合评价

基于2019年全国农业技术推广服务中心展示谷子部分登记品种的春谷早熟区和中晚熟区试验数据,对内蒙古自治区赤峰市和山西省晋中市展示点69个参试品种的主要农艺、产量和品质性状以及抗逆性进行比较与分析。参试品种与各自对照相比,产量变幅为4425~4942.5 kg,株高变幅为111.0~178.6 cm,籽粒蛋白质含量变幅为8.85%~15.47%,籽粒脂肪含量变幅为1.06%~5.69%,籽粒淀粉含量变幅为58.81%~86.8%,春谷早熟区生育期变幅为108~122 d,春谷中晚熟区生育期变幅为118~126 d。谷子品种展示评价体系,对谷子登记品种的生产性能进行综合评定,旨在为谷子品种的合理评判以及谷子的引种与推广提供科学依据。选育食味上佳兼具功能性的优质商品性品种和株高适宜机械化收获品种是今后谷子育种目标和方向。

Comprehensive Evaluation of Agronomic Traits,Quality and Yield of Spring Valley Varieties

Based on the test data of early and middle and late spring grain of millet registered in the National Agricultural Technical Extension Service Center in 2019,the main agronomic traits,yield,quality characters and stress resistance of 69 tested cultivars were compared and analyzed in two display points.Compared with the control,the yield of the tested varieties varied from 4425 to 4942.5 kg,the plant height varied from 111.0 to 178.6 cm,and the grain protein content varied from 8.85%to 15.47%.In addition,the grain fat content varied from 1.06%to 5.69%and the grain starch content varied from 58.81%to 86.8%.Simultaneously,the growth period varied from 108 to 12 days in the early maturing area,while the growth period varied from 118 to 126 days in the middle and late maturing area of spring grain.The production performance of registered millet varieties was evaluated comprehensively by using the display evaluation system of millet variety and it could provide scientific basis for reasonable evaluation of millet varieties and introduction and popularization of millet.It was the goal and direction of millet breeding to select high quality commercial varieties with good taste and function and cultivars with high plant height suitable for mechanized harvest.
