general combining ability
However, the characteristics of androgenesis were the highest in those hybrid combinations in which genotypes with high values of general combining ability (GCA) and positive effects of specific combining ability (SCA) participated.
      
Attempts to construct synthetic populations by combining self-fertile forms selected by general combining ability failed because of high-rate selfing.
      
General combining ability effects were more important for both characters.Per se performance appeared to be a good index to rank the parental lines for general combining ability.
      
The study indicated that both general combining ability and specific combining ability effects were significant and important for all three traits.
      
General combining ability seemed to be more important for all the characters.
      
The proportion of general combining ability variance was much higher than that of the specific combining ability variance although both were statistically significant.
      
Mean performance was correlated with the general combining ability effects.
      
General combining ability (GCA) was found to be the largest and most significant source of variation contributing to differences between crosses for all the traits, in both male and female birds.
      
Both general combining ability (G.C.A.) (2x) and S.C.A.
      
The effect of family structure is studied, and some consequences of interest to plant breeding are discussed by an application to general combining ability selection.
      
No clear association could be discerned between general combining ability (GCA) effects for grain yield and its components, and mean grain yield performance and GCA effects.
      
Estimates of general combining ability in Hevea breeding at the Rubber Research Institute of Malaysia
      
Estimates of general combining ability of parents for yield and girth obtained separately from seedlings and their corresponding clonal families in Phases II and IIIA of the RRIM breeding programme are compared.
      
Distinct differences were observed in general combining ability values for regression coefficients among the parents, indicating transmissibility of this trait.
      
The S5 partial diallel was as good as the S19 for the detection of differences among general combining ability (GCA) effects.
      
The relative breeding values of the parental varieties, as indicated by their general combining ability effects, did not vary much over the generations.
      
When a character has a large additive genetic component in its variance, general combining ability estimates may be used for predicting cross performance.
      
General combining ability (gca) was significant for all five characters; specific combining ability (sca) was significant for stalk diameter, stalk length, and plant volume.
      
Parents were evaluated on the basis of their general combining ability: clone H49-3533 had high gca for sucrose content, while clone H53-5356 had high gca for plant vigor.
      
Combining ability analysis showed that general combining ability (GCA) and specific combining ability (SCA) were both important in the expression of yield.
