Gene Action and Combining Ability Test for Some Agro-morphological Traits in Barley

Abstract:
Background and Objectives: Barley is one the most important crops worldwide mainly for food, feed and drinks including Ethiopia. The aim of this study was to assess the combining ability of barley parents and estimate the inheritance pattern for some agro-morphological traits for future breeding. Materials and Methods: This study was carried out on 28 barley genotypes (21 F1 and 7 parents) in a randomized complete block design with three replications during 2015 cropping season at Holetta, Ethiopia. Results: There was significant difference due to both GCA and SCA among barley genotypes for all the characters studied except for days to heading, days to maturity and grain yield per plant which had non-significant SCA revealing the predominance of additive gene effects to non-additive gene effects for all characters except for thousand kernel weight. Every barley parents were best general combiners for one or more important agronomic characters. Large range of heterosis values (-23.8 to 86 and -40.6 to 43.2%) for grain yield per plant over mid parent and better parent, respectively. Conclusion: The finding suggests that yield can be improved through multiple crossing of parents with best GCA effects for the desired characters followed by selection at later generation.
