摘　　要：根据小麦种质77中2882的试验和在育种中的应用情况，研究了该种质的主要特点及其应用效果。结果表明，77中2882是一个丰产、多抗、早熟、优质，并合1B／1R易位的优良冬春杂交小麦种质。它的丰产性、矮秆抗倒、抗病、多花乡杜和高蛋白质、高湿面筋含量等重要农艺性状，都能很好地遗传给7个衍生审定小麦品种。7个衍生品种累计推广130多万公顷。还提出了今后进一步挖掘利用该种质的重要意义和利用重点。Based on the performance of wheat germplasm 77 Zhong 2882 in the trinls and application in wheat breeding, this paper studied its main agronomic traits and application results as a wheat breeding material. The results showed that 77 Zhong 2882, derived from a cross of spring x winter type wheat, was a good wheat breeding germplasm with 1B/1R translocation.Its agronomic chatacteristics such as high productivity, dwarf and resistance to lodging, resistance to rusts, multi-florets and multi-grains. high protein and gluten contents were passed to 7 regisered wheat varieties derived from 77 Zhong 2882.These varieties coverd more than 1. 3 million hetares. The paper also stressed the importance in utilizing wheat germplasm and suggested that wheat breeders should utilize 77 Zhong 2882 as a pave in their wheat breeding program.
