| 摘 要： | 采用灰色关联度法分析了华北地区 2 0个谷子代表品种的农艺性状演变趋势。结果表明 :谷子株高逐渐降低 ,成穗率明显提高 ,穗长、单穗重、单穗粒重、千粒重发展协调 ,产量大幅度提高。谷子育种今后应以中秆中穗类型为目标 ,栽培管理应在提高成穗率的基础上主攻千粒重。

| Abstract: | Through summarizing the evolution tendency of 20 millet varieties developed in 4 different periods, the relative importance of the agronomic traits to yield in different periods was studied by means of Grey correlative degree. The results indicated that plant height gradually decrease, fertility rate obviously increase, spike length, spike weight, the weight of kernels per spike and thousand kernels weight correlatively develop, while the yield was greatly increased. The result of correlative analysis is basically in accordance with the traits evolution tendency. It is suggested that the object on the millet breeding program was to select middle plants and middle spikes, and the management of cultivation should be focused on thousand kernels weight in addition to promoting fertility rate. |
