Popis: The non-dormant character in Spanish and Valencia bunch type is undesirable for groundnut cultivation in summer season where at harvest stage of the crop rains are invariably received and cause heavy losses of produce by way of sprouting of pods in the field. It is more problematic in soil areas where moisture retention capacity is high. A loss of 20-50 per cent in bunch groundnut pod yield has been reported due to in situ germination. The search for investigation of non-conventional methods of inducing dormancy in bunch types to save the produce and to retain the seed quality against the field sprouting are of greater importance. In the Spanish bunch type, cultivars possessing 3-4 weeks dormancy will be able to save the field losses due to in situ sprouting when the mature crop is caught in untimely rains. Thus the non-dormant nature of bunch groundnuts, besides reducing the yield, also deteriorates seed and oil quality. Seed availability is also reduced because of field sprouting. The research on these aspects of induction of dormancy in bunch groundnut to avoid losses during rainy season has been reviewed in this article.
