多数研究报道认为,小麦与玉米、高粱一样,具有较强的杂种优势.但是根据国外在七十年代初期的试验结果,小麦杂种优势不能令人满意,在产量上远远没有达到预期的目标,其主要原因在于亲本选配不当.近年来国外报道,利用不同生态型的丰产品种进行杂交,能获得最好的产量优势.本试验通过春性和冬性两类不同生态型的品种间杂交,连续进行二年杂种一代的优势测定,为有目的地选配杂交亲本提供依据. Most studies report that wheat has the same strong heterosis as corn and sorghum, but according to the results of experiments abroad in the early 1970s, the heterosis of wheat is unsatisfactory and the yield is far from the expected goal. The main reason is that parents choose improper.In recent years, foreign reports, the use of different ecotypes of high yielding varieties of hybrids, can get the best yield advantage.This experiment through two types of spring and winter ecotypes of hybrids , For two consecutive years to determine the advantages of hybrid generation, to provide the basis for the purpose of optional hybrid parents.
