ISHS Acta Horticulturae 218: XII African Symposium on Horticultural Crops

EVALUATION OF SEVERAL ONION CULTIVARS FOR DEHYDRATION PURPOSES

Author:   G. Mohamedali
Abstract:
Five field experiments were conducted in 1977–82 with the object of testing the suitability of several onion introductions and local cultivars for the dehydration industry in Sudan. The introductions included 'White Creole', 'Dehyso' (a selection from 'Southpart White Globe'), both being leading dehydration cultivars in the U.S.A., and 'Primero 14'. The local cultivars included 'Nasi', 'Shendi Yellow', 'Suleim 42/43', 'Dongola Early' and 'Dongal 9'. Results of the studies indicated that the introductions were inferior in yield, susceptibility to doubling and in both soluble solids and dry matter percentages than local ones. The introductions were also late and of poor keeping quality compared to local ones. Four local cultivars, 'Nasi' (white), 'Shendi Yellow', 'Dongola Early' (yellow) and 'Dongola 9' (yellow) proved to be equally suitable to serve the hydration industry in the Sudan.
