ABSTRACT

Avocado is a member of the Lauraceae family. It is a crop with enormous economic significance all over the world. The aim of this work was to evaluate the performance of avocado cultivars for yield and yield components. Six avocado cultivars and one local check cultivar were compared in Teppi Agricultural Research Center. The experiment was laid out in randomized complete block design with three replications. The analysis of variance showed that, for most growth traits except girth above union and girth below union, significant variation has been recorded. The combined analysis over seasons revealed that significant difference between cultivars for most of the characters tested. The over years combined analyses of variance revealed that there was significant difference (P < .05) among cultivars for yield performance. Among the cultivars, the highest yield (29.13 tha⁻¹) was recorded for Ettinger. In contrast, the lowest yield was recorded for local (6.20 tha⁻¹). The cultivars, Ettinger, Hass and Fuerte performed better as compared to other cultivars. Therefore, these cultivars should be multiplied and disseminated for further popularization. The gaps in cultivar improvement, agronomic management and post-harvest handling also need due attention to improve the productivity of avocado in target area.

摘要

鳄梨是樟科植物的一员。它是一种在全世界具有巨大经济意义的作物。这项工作的目的是评估鳄梨品种在产量和产量构成方面的表现。Teppi 农业研究中心比较了六个鳄梨品种和一个本地检查品种。实验采用随机完整区组设计，重复 3 次。方差分析表明，对于除联合以上周长和联合以下周长以外的大多数生长性状，记录了显着变化。跨季节的综合分析表明，对于大多数测试的性状，品种之间存在显着差异。历年组合方差分析显示存在显着差异（P < .05) 在品种间的产量表现。在这些品种中， Ettinger 的产量最高 (29.13 tha ^{-1 )。}相比之下，当地记录的产量最低 (6.20 tha ^-1 )。与其他品种相比，Ettinger、Hass 和 Fuerte 品种表现更好。因此，应大力推广推广这些品种，进一步推广。品种改良、农艺管理和收获后处理方面的差距也需要给予应有的重视，以提高目标地区鳄梨的生产力。
