Abstract
The recombination frequency was measured between two linked marker loci a (anthocyaninless) and hl (hairless) in control and irradiated developing buds in Cluster I on the main stem in tomato. The buds which corresponded to early prophase I of meiosis showed significant increase in recombination frequency after gamma irradiation at a stimulating dose level (72R). Besides, the response was similar for all bud development stages tested. Treatment of buds with 0.005 per cent pyronin Y during early prophase of meiosis did not produce consistent results.
