  4. In the study, six different ecotype varieties of common wheat and f1 derived from 6 6 complete diallel crossing system were selected for the research on the characteristics and heterosis of spike differentiation. the results showed that heterosis existed in most key spike differentiation phases and varied with different ecotype varieties. heterosis of spike differentiation was positively correlated with heterosis of hybrid yield. finally, the author concluded that it was the best way to produce strong heterosis combination by selecting the mode of “ spring wheat winter wheat ” in huanghuai winter wheat region

    對6個不同生態類型小麥品種及其完全雙列雜交f1幼穗分化特點和穗分化雜種優勢的研究表明，雜種幼穗分化各主要時期普遍存在雜種優勢；不同生態類型組配方式的雜種穗分化優勢不同；穗分化雜種優勢與產量雜種優勢具有一定相關關系；黃淮麥區雜交小麥最佳生態組配方式為春性品種冬性品種。
