摘 要:经多年试验,豫麦33号产量比豫麦17号增产4.4%~8.5%,居一、二位。抗多种病害,具有丰产、早熟、适应性广的特点。该品种的选育表明,采用生态类型差异较大的南、北品种杂交,其后代表现广泛分离;冬春性小麦杂交可丰富其遗传基础;复合杂交有助于优良基因的组合和累积,这是选育抗病、高产品种的一个有效方法。Tested in many years, wheat variety Yumai 33 had a yield of 4. 4%-8. 5% higher than the check variety Yumai 17 and is characterized as resistance to diseases, high yielding,early-maturity and extensive adaption. It came from a 3-cross hy-brid , which had 3 parents with various ecological types and from southern and northern parts of China separately. For this reason,the cross had an abundant genetic basis and produce diverse offsprings, some of which have genes resistant to various diseases form different parents. This is the effective method to select varieties with high-yielding and resistance to diseases.
