Larger seeds of chickpea (Cicer arietinum) and pigeonpea (Cajanus cajan) gave rise to larger seedlings than did smaller seeds. When approximately half the cotyledonary reserves from pigeonpea seeds were removed, seedling weight was reduced to about half of the controls, suggesting that seedling growth was related to the reserve material in the seeds. Seed-grading had no significant effect on the yield of either of these crops grown on a Vertisol and on Alfisol in Andhra Pradesh, or on an Entisol in Haryana or in the Lahaul valley of the western Himalayas. Seeds harvested from pigeonpea grown from larger seeds were significantly heavier than those from plants derived from small seeds, probably because of the genetic heterogeneity of the varieties.
