Heterosis and Combining Ability on Field and Quality Characters of Chickpea (Cicer arietinum L.)

Mohammed Y. Al-Fahady, Maan M. Al-Badrany


Seven parents of chickpea (Cicer arietinum L.): Local, F85, F97-73c, Dijla, Marakishi, IPA69 and F97-158 were crossed in diallel fashion (excluding reciprocals). The seeds of parents and F1’s were sown during the season 2005-2006 in the field of the college of Agric. and Forestry at Mosul University. The results can be summarized as follows: Heterosis measured as deviation of F1 from the best parent showed significant values for number of days to 50% flowering and 90% maturation, number of seeds per pod and seed yield in (F97-73c x Dijla) hybrid. The variance due to general and specific combining ability was significant at 1% level for all characters. The ratio of the general to specific combining ability components was less than one for all characters, except for 100-seed weight, where it was more than one. This result refers to the importance of non-additive effect for these characters. The parents (F97-158c) exhibited significant general combining effects for number of days to 50% flowering and 90% maturation, number of secondary branches and seed yield.
