Development of early maturing lentil varieties is an im­portant aim in lentil breeding program at ARC. Egypt. The present study aimed to estimate variability, heritability, and genetic ad­vance from selection for earliness and seed yield characters for 24 lentil genotypes to provide information that could be useful in len­til breeding programs. The experiments were carried out at Sids re­search station in 1997/98 and 1998/99, and at Giza research sta­tion in 1998/99 season. The environments (season and location) showed major effects on the performance of genotypes. High phe­notypic variation was observed for number of pods and seeds/plant. Considering wide variability, heritability and genetic advance, progress could be expected from selection for number of seeds/ plant and seed yield/plant. The early maturing genotypes Sina 1, FLIP 87-21L and FLIP 92-54L could be recommended for planting in case the earliness in maturity is more important than seed yield. On the other hand, the high yielding genotypes FLIP 89-71L, FLIP 95­68L, 89503, FLIP 92-48L and FLIP 95-501. could be recommended for planting in case the high yield potential is more important than earliness in maturity.
