利用１２个杂交组合对Ｔ型春性杂交小麦的株粒数、株粒重、株穗数、主穗小穗数、千粒重、穗长６个主要性状进行了超标优势分析，结果表明：所有组合的株粒重、株穗数、千粒重、穗长４个性状具有明显的正向超标优势，株粒数、主穗小穗数２个性状的超标优势表现为正负优势且幅度较大，分别为－１９．２％～５６．５％、－２．１％～５．３％之间。采用配合力的同亲回归分析，克旱９Ａ和克８２Ｒ２７特珠配合力最高，其次为克丰二Ａ×克８２Ｒ６７、克丰三Ａ×克８２Ｒ２７。用２个春性Ｔ型杂种小麦和２个化学杂交剂制成的ＣＨＡ杂交小麦，３个亲本（其中２个为对照品种）共７个品种，研究了群体密度对春性杂交小麦主要性状及其杂交优势的影响，明确了春性杂交小麦适宜的密度范围，为合理利用杂交小麦的优势效应采取高产高效的栽培措施
Twelve hybrid combinations were used to analyze the over-standard predominance of six main traits of T-type spring wheat, including the number of grain per plant, grain weight per plant, spike number per spike, spikelet per spike, grain weight per spike and spike length. The results showed that: The grain weight, panicles per panicle, grain weight per panicle, panicle length and panicle length had obvious positive over-standard advantage. The over-standard superiority of two traits, For -19.2% ~ 56.5%, - 2.1% ~ 5.3%. With the regression analysis of the combining power of cousins, KAREN 9A and 82R27 special beads with the highest combining ability, followed by grams of two A × grams 82R67, grams of three A × grams of 82R27. A total of 7 varieties of CHA hybrid wheat and 3 parents (2 of which were control varieties) were made from 2 spring T hybrid wheat and 2 chemical hybrids. The effects of population density on the main characters of spring wheat, Its hybridization advantage, clear spring suitable hybrid wheat density range, to take advantage of the dominant effect of hybrid wheat to take high yield and efficient cultivation measures
