This study aimed to evaluate 20 lentil genotypes for their perfor­mance and yield potential in the new reclaimed lands at Abu-Simbel and to estimate the genetic parameters, which help for further selection in this location. The genotypes were planted in November at three seasons (1999/2000, 2000/2001, 2001/2002). Significant differences oc­curred among seasons due to the wide variation in maximum and mini­mum air temperatures and relative humidity, which affected accumula­tion of plant dry matter and yield performance of genotypes. Thiele genotypes FLIP 95-68L, FLIP 86-7L and FLIP89-71L out yielded the check cultivar Giza 9 by 32.3, 24.6 and 19%, respectively. In addition they had high harvest index values of 38.4, 31.3 and 29.8%, respective­ly. These genotypes also had higher seed yield/plant, number of pods and seeds/plant, and hence being promising and could be recommended for planting at Abu-Simbel after verification and large-scale on-farm trials. High estimates of phenotypic coefficient of variation, broad sense heritability together with genetic advance for seed yield/plant and har­vest index, suggesting that pronounced progress should be expected from selection among genotypes for these characters at Abu-Simbel.
