ANALYZING COMBINING ABILITY AND HETEROSIS OF THERMOPHOTO SENSITIVE GENIC MALE STERILE WHEAT LINES FOR HYBRID DEVELOPMENT

An estimation of the combining ability of barley genotypes and heterosis for some quantitative traits

ABSTRACT- Barley (Hordeumvulgare L.) is one of the most important cereals in the world which is used as human and cattle feed and for malt production. One of the most important steps in a hybrid and selection breeding program of barley is the selection of suitable parents with high general (GCA) and specific combining ability (SCA) for grain yield. In order to estimate the combining ability and...

general yield and specific combining ability and heterosis of some cucumber lines in partial diallel design

combining ability and heterosis were studied in a 6×6 partial diallel cross during 2007-2009 to see the nature of gene action in cucumber (cucumis sativus l.). analysis of variance revealed high significant differences among all the f1 hybrid means and among their respective six parental values for all the traits examined. the mean squares attributed to general combining ability (gca) and speci...

Hybrid Performance from Male-Sterile and Pollinator Inbred Onion Lines

QTL Mapping of Combining Ability and Heterosis of Agronomic Traits in Rice Backcross Recombinant Inbred Lines and Hybrid Crosses

BACKGROUND Combining ability effects are very effective genetic parameters in deciding the next phase of breeding programs. Although some breeding strategies on the basis of evaluating combining ability have been utilized extensively in hybrid breeding, little is known about the genetic basis of combining ability. Combining ability is a complex trait that is controlled by polygenes. With the ad...

general and specific combining ability and heterosis estimation of some cucumber lines for qualitative traits in partial diallel design

partial diallel design can be used to investigate the general and specific combining ability, and heterosis. combining ability and heterosis were studied in a 6×6 partial diallel cross to see the nature of gene action for fruit quality indices in cucumber (cucumis sativus l.) during 2007 to 2009. analysis of variance revealed highly significant differences among all the f1 hybrid means and thei...
