Effect of genotype and storage duration on onion commodity parameters

Stefka Genova, Gaina Pevicharova

Abstract: The suitability for long-term storage in the storehouse under ambient conditions of eight onion cultivars of three types: with white, red and yellow envelope flakes was studied at the Maritsa Vegetable Crops Research Institute in Plovdiv during 2015 -2016 period. The traits weight loss and percentage of healthy bulbs were analyzed. It was found a dominant influence of storage duration on them. Genotypic expression was observed for both commodity parameters. Diamond x Granada line was the most promising for long-term storage because of the lowest percentage of losses and a significantly high percentage of healthy bulbs after six months of storage. A moderate positive correlation (r = 0.596 **) was found between the dry matter content after harvest and the percentage of healthy bulbs at the end of the experiment.
