| Abstract | ||
| The present study was carried out at Shandaweel Agricultural Research Station, Sohag Governorate, Egypt during the period of 2009-2011 summer seasons. The means of selected families after two cycles of early selection for seed yield/plant ranged from 31.88 to 43.50 with an average of 37.36 compared to 17.83, 25.47 and 23.33g for P1, P2 and bulk sample in population I, respectively. Likewise, these means varied from 29.33 to 39.67 with an average 34.03 compared to their respective parents P1 (19.00) P2 (29.00) and bulk sample (30.0g) in population II. The average of seed yield/plant overall selected families of 41.24 and 42.37 after one cycle of late selection surpassed their averages of 37.36 and 34.03 g after two cycles of early selection by 10.38 and 24.51% for population I and II, respectively. The slight discrepancy between (GCV) and (PCV) resulted in high estimates of broad sense heritability for most studied traits in the two base populations. The selection response to one cycle of late selection for seed yield/plant was large comparing to their values after two cycles of early selection in both populations. The values accounted 61.94 and 76.74 % in population I and 46.11 and 41.24 % in population II with late selection comparing to 46.70 and 60.11 % in population I and 17.36 and 13.44 % in population II as a deviation from the best parent and bulk, respectively. | ||
