| 中文摘要: |
| 平凉42号是以应用显性雄性核不育单基因（Ms2）和显性矮秆基因（Rht10）连锁控制的“矮败”小麦为材料，在Tal长武131//［平凉38号/82（51）F3］组合中选育而成的冬小麦新品种。该品种在甘肃省冬小麦区试三年27点次平均产量3 321.45 kg·hm-2，较对照兰天4号增产9.5%，株高77.5 cm，千粒重38.9 g，籽粒粗蛋白含量13.03%～15.19%，赖氨酸0.46%～0.48%，条锈病情指数0～43.12%，越冬率92.32%，抗旱系数0.83，水分利用率10.7 kg·mm-1·hm-2。具有高产优质、抗旱节水、抗病耐冻等优良性状，适宜在陇东黄土高原旱地、河谷川台中等以上肥力地块上种植。 |
| 英文摘要: |
| Pingliang 42, a novel resistance to drought variety, was developed using a dwarf male-sterile wheat, which containing Ms2 and Rht10, drived from Tal-Changwu 131//〔Pingliang 38/82(51) F3〕. In Gausu Province cultivar comparison trails, the average yield of Pingliang 42, three years and 27 locations, were 3321.45 kg·hm-2, increased 9.5% in comparison with that of the control cultivar, Lantian 4, plant height 77.5 cm; 1000 grain weight 38.9 g; Crude protein content of grain 13.03%～15.19%; Lysine content 0.46%～0.48%; stripe rust index 0～43.12%; over wintering frequency 92.32%; drought-resistant coefficient 0.83; Water use efficiency 10.7 kg/(mm·hm2). It indicates that the characters of Pingliang 42, super high yield and good quanlity, excellent resistance to diseases, tolerant to drought and low temperature. Pingliang 42 is a desirable cultivar in the dryland of Loess Plateau areas of Eastern Gansu and in the middle-fertility level fields of the terrace of river valley. |
