摘要: 以华北夏谷生态区近年育成的8个夏谷新品种的单株性状表现为基础,结合传统的夏谷单株选择理论和育种目标对各性状的要求,对与夏谷单株产量密切相关的8个性状分别制定了选择标准。按此标准,运用改进列联表法,对1992~1993年选择的1088个优良单株进行统计分析,将单株综合性状选择指标数量化,建立了夏谷高产育种单株选择模式。经验证,该模式在夏谷育种中具有一定的应用价值。

Abstract: Basing on the individual characters of 8 summer millet varieties of Huabei summer millet ecotype,combining the requirements of traditional individual selection theories and breeding objectives to the characters,the selective standards of 8 characters directly related to summer millet individual yield were drawn up respectively .According to the standards, making a statistics analysis by use of the improved contingency table method with the data of individuals selected during 1992 to 1993,the quantified comprehensive selection indexes and a model of individual selection on summer millet for high-yield breeding are proposed. Practice proves that the model is useful for summer millet breeding.
Key words:
Summer foxtail millet,
High-yielding breeding,
Individual selection model
