SCREENING OF ONION BREEDING SELECTIONS
FOR STORING ABILITY
In the paper there are presented the results of an experimental study
of onion breeding for storability.
Introduction
In 2012 onion has ranked as one of the major vegetable crops in Kazakhstan
occupying 22,9 thousand ha [1]. Onions are an essential part of the human
daily diet and consumed year round. Production of bulb onion in our country
is limited to a late summer-early autumn period, so consumer demand is met
by supplying it from storage for 8-10 months. Therefore, the disease resistance
of the crop, particularly in storage season is of great importance. However, a
significant part of the crop that is put in storage can be lost due to bulb rot.
The most effective method of plant protection against infectious diseases is
to develop and release of disease resistant varieties for fresh market, which
would greatly reduce the yield loss in storage. Therefore, breeding programs
should be aimed not only to enhance the productivity and quality of grown
products, but also to improve the resistance of plants to disease and keeping
ability in storage, which is especially imperative in the ever increasing role
of the limited application of pesticides.
