Abstract

The production and productivity of malt barley are limited using disease-susceptible and low-yielding varieties. Study was focused on identifying and selecting the best performed and adapted malt barley variety/varieties for yield and yield-related traits. We evaluated six improved malt barley varieties using a randomized complete block design with three replications. The study was conducted for 2 years (2019 and 2020 cropping season) at Lay Gayint district. The combined analysis showed highly significant differences ( P < 0.01 ) among varieties, years, and their interactions in all traits. The highest yield (31.54 qt·ha−1) was obtained from variety Holker. The correlation coefficient analysis showed a significant and very strong positive association of grain yield with number of effective tillers ( r = 0.953 ∗ ∗ ), spike length ( r = 0.973 ∗ ∗ ), and strong positive association with thousand seed weight ( r = 0.739 ∗ ∗ ) with a medium positive association with seed per spike ( 0.554 ∗ ∗ ). In principal component analysis, PC1 was dominated by traits that had a greater effect on yield. A variety of Holker could be recommended in the study areas and other similar agro-ecologies. Farmers lost a lot of quintals of yield by lack of new technologies, by addressing more adapted improved production technology increased average yield.

麦芽大麦(Hordeum districhon L.)的评价埃塞俄比亚贡达尔南部产量和农艺性状品种

使用易感病害和产量低的品种限制了麦芽大麦的生产和生产力。研究的重点是鉴定和选择表现最佳、适应性最强的麦芽大麦品种，以获得产量和产量相关性状。我们采用三次重复的随机完全区组设计对六个改良麦芽大麦品种进行了评价。这项研究在莱加因特区进行了两年（2019年和2020年种植季节）。综合分析表明，各性状在品种、年份及其相互作用之间存在极显著差异（P<0.01）。最高产量（31.54 qt·ha−1）。相关系数分析显示，粮食产量与有效分蘖数（r=0.953**）、穗长（r=0.973**）呈显著且非常强的正相关，与千粒重呈强正相关（r=0.739**），与每穗种子呈中等正相关（0.554**）。在主成分分析中，PC1以对产量影响较大的性状为主。可以在研究区域和其他类似的农业生态中推荐各种Holker。由于缺乏新技术，农民损失了五分之一的产量，通过采用更适应的改良生产技术提高了平均产量。
