Abstract

Investigations were carried out to understand the intor-relationship of seed sizo with physico-chemical characteristics in groundnut cv. POL1 and TMV 2. The large size seeds retained by 21/64" and 20/64" diameter round perforated sieves possessed significantly high 1000 seed weight and weight of primary axis, but the per cent weight of primary axis to weight of cotyledons was high in small size seeds retained by 18/64" and 16/64" diametor round perforated sieves. The EC value of leachate increased with increase in seed size. Though it is contradictory to the accepted vigour concept it may be attributed due to lack of membrane integrity in large seeds of groundnut due to invisible cracks developing during processing. The protein content and total free fatty acid content showed positive correlation with seed size. The oil content exhibited negative relationship in both the varieties.
