通过对化杀杂种小麦组合０００４Ｒｄ／８４１２９ｄ３、２０１５／ＮＣ３３２、３３２ｄ／分３３和３３２ｄ／８４－１Ｆ２的主要农艺性状与其双亲、Ｆ１、对照品种（小偃６号和陕２２９）和４个杂种Ｆ２组合之间的相互比较分析，结果表明，３３２ｄ／８４－１的化杀杂种Ｆ２具有抽穗期较早，扬花持续时间短，株高间分离程度较低，穗长均匀，成穗率较高的特点，产量也表现出较高的杂种优势，相对于其它３个化杀杂种Ｆ２来讲，是一个较好的组合，可利用于大田生产和示范。有希望用于生产的Ｆ２和Ｆ１代产量构成因素的杂种优势依次为：穗粒数＞单株穗数＞千粒重。选配组合中，应注意产量性状突出的亲本利用。结合多年的观察和实践，化杀Ｆ２要利用于生产，还必须具有以下几个特点：大田产量应超过对照品种１０％以上；株高差异在３０ｃｍ以内；成熟期差异不超过４ｄ。
The main agronomic traits of 0004Rd / 84129d3, 2015 / NC332, 332d / 33 and 332d / 84-1F2 were compared with their parents, F1, control varieties (Xiaoyan 6 and Shaan 229) and 4 hybrids F2 The results showed that 332d / 84-1 hybridized F2 had the characteristics of earlier heading date, shorter flowering duration, lower degree of segregation among plant height, uniform spike length and higher spike rate Characteristics, yield also showed higher heterosis, relative to the other three kill hybrid F2, is a good combination, can be used for field production and demonstration. The heterosis of F2 and F1 yield components that are expected to be used for production are as follows: Spikelets per plant> Spikes per plant> 1000-grain weight. Matching combinations, should pay attention to the output traits prominent parental use. Combined with years of observation and practice, F2 should be used to kill production, but also must have the following characteristics: field output should exceed 10% of the control varieties; plant height differences within 30cm; maturity differences of not more than 4d.
