杂交小麦的培育和研究,是近二十多年来小麦育种的一项新课题。目前世界上至少有二十多个国家进行这方面的研究。杂交小麦要投入生产,必须具有较强的杂种优势,其产量要显著超过当地推广品种。为了尽快选配出具有强优势的杂交组合,发掘具有较高配合力的亲本,我们对具有不同生态特点的五个优良小麦品种(P=5),进行双列杂交试验,对其杂种优势和配合力进行初步研究。 Breeding and research of hybrid wheat is a new subject of wheat breeding in the recent two decades. At present, there are at least more than twenty countries in the world to conduct research in this field. Hybrid wheat to be put into production, we must have a strong heterosis, its output should significantly exceed the local promotion of varieties. In order to identify the hybrids with strong heterosis as soon as possible and explore the parents with higher combining ability, we conducted the double-row hybridization test on five elite wheat cultivars with different ecological characteristics (P = 5) Combining ability to conduct a preliminary study.
