Abstract
Certified and farmer saved seeds for one year are suggested for wheat production but seed resulted from further regenerations of farmer- saved seed should be neglected. The present study aimed to verify genetic purity and planting value of three wheat cultivars using morphological , physiological and biochemical characters as well as grain yield of each tested cultivar . Two field trails were carried out at El-Gemmiza experimental station, Delta region,Egypt, during 2002/03 and 2003/04 growing seasons and laboratory tests were conducted in parallel at Seed Technology Research Section, Agricultural Research Center, Giza, Egypt.The results indicated that the percentage of off-types , and diseased plants increased as the farmer relied on himself for preparing seeds for crop production.The grain yield and genetic purity based on number of off-types and seed fingerprint were significantly reduced from planting second genration of farmer-saved seeds compared with those from standard and certified seeds. It is possible to utilize farmer-saved seed for one year (first generation of certified seed , farmer's previllage), provided that the farmer takes out the off types from the part of his field he keeps for next planting.Planting value of seed from different sources as measured by laboratory tests including germinability and electrical conductivity, and field performance of the seed came to the same condusion.
