摘要

有必要利用改良品种来提高大麦的产量潜力。因此，本研究旨在评价大麦基因型在物候和产量性状上的表现。在尼泊尔的Lumle, Kaski进行了一项实地研究，涉及7种大麦基因型，在2018/2019和2019/2020两个生长季节，采用重复三次的RCB设计。综合历年结果，除有效分蘖/m2和千粒重外，其他性状均存在显著差异。籽粒产量最高的品种为B86122-1-0K-3 (2.756 t/ha)，与Xveola-28 (2.411 t/ha)和B90K-024-1-1-2-0K (2.350 t/ha)相当，显著高于Bonus(标准对照)(1.852 t/ha)。这些优越的基因型应在尼泊尔西部丘陵的站点和农场条件下进一步评价，以便改善尼泊尔低和停滞的大麦产量

Evaluation of Different Barley Genotypes for their Phenological Traits, Yield and Yield Attributes in the Western Mid-Hill of Nepal

There is a need to increase the yield potential of barley by utilizing improved cultivars. So, the present study was done to assess the performance of barley genotypes for phenological and yield attributing traits. A field study was carried out at Lumle, Kaski in Nepal involving seven barley genotypes during two growing seasons in 2018/2019 and 2019/2020, employing RCB design replicated three times. The results, combined for the years, showed significant differences for all traits except effective tillers/m2 and thousand grains weight. The grain yield was highest for B86122-1-0K-3 (2.756 t/ha and was at par with the genotypes Xveola-28 (2.411 t/ha) and B90K-024-1-1-2-0K (2.350 t/ha) and significantly higher than the Bonus (standard check) (1.852 t/ha). These superior genotypes should be further evaluated at on-station and on-farm conditions of western hills of Nepal so that low and stagnating barley yield in Nepal can be improved
