所谓小麦染色体(注1)减倍育种,就是对于小麦的远缘杂交后代,改变染色体结构,缩减染色体倍数的育种方法。我们是从1973年以来,才开展了此项研究工作的.第一批材料今年是杂种第4代(F4),选获了一批株高70—80厘米,籽粒饱满,千粒重50克上下,对白粉病,锈病免疫,既有八倍体小黑麦根系发达、适应性广的优点,而又排除了小黑麦植株过高、晚 The so-called wheat chromosome (Note 1) double breeding, is for the distant hybridization of wheat offspring, change the chromosome structure, reduce the chromosome multiplication breeding method. We started this research work since 1973. The first batch of materials is the 4th generation of hybrids (F4) this year, and we have won a batch of 70-80 cm of plant height, full grains and 50 g of grain weight, Powdery mildew, rust immunity, both the octagonal triticale root developed, the advantages of wide adaptability, but ruled out the triticale plants too late, late
