Abstract
In mutation breeding experiments at our laboratory several mutants with large seeds having greater seed weight in comparison to their respective parental cultivars have been isolated. These have been breeding true for several generations, maintaining the characteristic increased seed size under different agro-climatic conditions. Three such mutants, one each in groundnut, pigeon pea and black gram and a mutant derivative of groundnut were analysed for studying the contribution of cotyledonary cell volume and cell number to the large seed character. Transverse sections of cotyledons and free cell suspensions were used for this purpose. In all the four genotypes with large seeds the volume, but not the number of cotyledonary cells, was significantly greater than in the respective parents.
