| 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. |
