2021—2022年度甘肃省胡麻新品系区域试验总结

Overview of the Regional Trial of New Flax Lines in Gansu Province in 2021-2022

为选育出丰产性、适应性和抗逆性强的胡麻新品种,甘肃省有关育种单位将新选育的胡麻新品系(组合)进行多年、多点试验综合评价,为新品种的登记和推广应用提供试验依据。结果表明,新品系SB2101(1450-35-1)2年16点次试验折合亩产为125.83 kg,较对照增产17.00%,居参试材料第1位;16点次试验中,有13点次增产,增产点占81.25%;丰产性最好、稳定性较好,高抗枯萎病。SB2109(1310-6)2年16点次试验折合亩产为112.89 kg,较对照增产4.97%,居参试材料第2位;16点次试验中,有12点次增产,增产点占75.00%;丰产性好,稳定性一般,高抗枯萎病。这2个新品系的综合评价较好、表现突出,在甘肃范围内可推广种植。

In order to select new flax varieties with high yield,adaptability and stress resistance,the new flax lines(combinations)were comprehensively evaluated by relevant breeding units in Gansu Province for many years and multi-point tests.to provide experimental basis for the registration,popularization and application of new varieties.The results showed that the yield per mu of the new strain SB2101(1450-35-1)was 125.83 kg at 16 points in two years,which increased by 17.00%compared with the control,ranking first among the tested materials.In the 16-point experiments,the yield was increased at 13 points,accounting for 81.25%.The yield is the best,the stability is good,and the wilt resistance is high.In SB2109(1310-6),the yield per mu was 112.89 kg,which was 4.97%higher than that of the control,ranking second in the tested materials.In the 16-point experiment,the yield was increased at 12 points,accounting for 75.00%.The yield was good,the stability was general,and the resistance to fusarium wilt was high.The comprehensive evaluation of these two new strains is good and their performance is outstanding,which can be popularized and planted in Gansu.
