１９９１～１９９２年度，采用相关分析、分级通径分析与组合类型分析方法，研究了１９个ＣＨＡ杂种小麦的产量、产量构成及其相互关系。结果表明，山西晋南麦区ＣＨＡ杂种生态型应为冬性或半冬性的以多粒为主兼顾粒重的重穗类型；高产杂种来自高产双亲；晋南麦区选择双亲都为高产水平的“重穗型×多穗型”、“中间型×中间型”、“重穗型×中间型”的配组模式，出现强优势组合的机率可能大些，配组亲本中，重穗型应选择多粒大粒重稳型或多粒重穗型，中间型应选择多粒中间型。
From 1991 to 1992, the correlation analysis, graded path analysis and combination type analysis were used to study the yield, yield components and their correlation of 19 CHA hybrid wheat. The results showed that the ecotypes of CHA hybrids in Shanxi Jinnan wheat region should be winter or semi-winter, with the main grain weight and the heavy grain type. The high-yielding hybrids were from high-yielding parents. Both parents were in high-yielding families Of the “heavy panicle type × multiple panicle type”, “intermediate type × intermediate type”, and “heavy pan type × intermediate type”, the probability of the emergence of strong dominant combination may be larger, Should choose more grain size heavy or heavy grain panicle type, intermediate type should choose more grain intermediate.
