Abstract

The storage of bulbs of onion (Allium cepa L.) is very crucial to ensure its availability throughout the year. Experiments were conducted at Sokoine University of Agriculture to evaluate the growth and yield characteristics of some tropical short–day onion cultivars and the storability of their bulbs after harvest. The first experiment in 1994 involved 21 cultivars evaluated for their growth and yield variables. The second experiment, involving six cultivars, was carried out in 1996 and in addition to performance evaluation, the storability of bulbs was investigated. Results showed significant differences among the cultivars in yield, yield components and storability. Granex 429 had the highest yield among cultivars in both trials, but had very poor storability. Serrana and XPH 6074 had long storability and maintained more than 50% of their weight after 5 months of storage. These two cultivars are promising as good sources of genes to incorporate storage traits in other cultivars of onion

热带短日洋葱(Allium cepa L.)栽培品种田间性能及贮藏评价

洋葱(Allium cepa L.)鳞茎的储存是确保其全年供应的关键。在索科因农业大学进行了试验，以评价一些热带短日照洋葱品种的生长和产量特征及其收获后鳞茎的储存性。1994年的第一次试验涉及21个品种，对其生长和产量变量进行了评估。第二次试验于1996年进行，涉及6个品种，除性能评价外，还对球茎的贮藏性进行了调查。结果表明，不同品种间在产量、产量构成和贮藏性方面存在显著差异。Granex 429在两个试验中产量最高，但贮藏性很差。Serrana和xph6074贮藏时间长，贮藏5个月后保持重量50%以上。这两个品种有望成为其他洋葱品种整合贮藏性状的良好基因来源
