HETEROSIS AND COMBINING ABILITY EFFECTS FOR SOME TRAITS OF PEA (Pisum sativum L.)

Abstract: This study was carried out at the college of Agriculture field, University of Duhok, during 2013-2014 growing season. It involved half diallel crosses among five genotypes of pea.The seeds of genotypes (parents and F1 hybrids) were grown according to Randomized Complete Block Design with three replications, to estimate general combining ability effects of the parents and specific combining ability effects of hybrids, heterosis as deviation from mid and better parents for the following characters, Days to 50% f… Show more

“…El -Dakkak [13] found negative heterosis (-16.82%) based on the tallest parent for this trait. Significant positive heterosis based on an early parent was observed in all garden pea crosses for days to the flowering trait [14], while, Askander and Osman [15] found negative heterosis in some crosses and positive heterosis values in the others. The data from these studies provide an opportunity to combine appropriate traits in one genotype and increase the efficiency of the breeding activity [16].…”
