Abstract

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.
