| Abstract | ||||
| The present study was carried out during the period from 2017 to 2020 under unheated greenhouse at the Experimental Farm (Kaha), Horticultural Research Institute ARC, Egypt. Six diverse lines of hot pepper, viz., P1 (C11), P2 (H 2), P3 (R 27), P4 (C4), P5 (H17) and P6 (C6) were produced by the author of the present study via selfing. The six lines were crossed in a half diallel mating to produce 15 F1 hybrids without reciprocals to estimate combining ability (general and specific) and heterosis percentage relative to both mid and better parents for some characters in pepper . Substantial mid-parent heterosis (MP) and high-parent (Heterobeltiosis) were obtained for the majority of studied characteristics. Mid- parent heterosis gave high and positive heterosis for average fruit weight, while heterobeltiosis was high and negative for fruit length, total soluble solids (TSS) and total yieldbut for plant height it had low percentage. Among the parents P3was good general combiner and could be used to improve these traits in pepper breeding programs by the accumulation of favorable genes. The cross (P1×P6) achieved high (SCA) effects for all studied traits. | ||||
