CONSTRAINTS FOR SHALLOT, GARLIC, AND WELSH ONION IN INDONESIA: A CASE STUDY ON THE EVOLUTION OF ALLIUM CROPS IN THE EQUATORIAL TROPICS
The absence of seed-propagated allium crops in the equatorial zone between latitudes 8° N and 8° S may be due to the unfavourable conditions for seed production and plant raising and consequently for local breeding. Modern technology might overcome these limiting factors. Commercial seed of adapted varieties in situ could be done in another region with a suitable climate. The prospects for a partial replacement of bulb shallot by true-seed shallot and/or by sowing onion, and of the traditional type of Welsh onion by a seed propagated type, are discussed.
Recommendations are given on on-farm client-oriented research (OFCOR) as a strategy for allium research and development at the national agricultural research systems (NARS), on cooperation with NARS in other tropical areas, and on the technical backing needed from more advanced institutes.
