Principles for Griffing's combining ability analysis
Genetica, 1993Griffing's diallel analysis is used in plant improvement programs to identify superior parents for crossing and for characterizing general, specific, and reciprocal effects. Eight different model/method combinations are commonly used in the analysis. The accuracy of the analysis is improved by using the appropriate model and method.

Combining ability for aluminium tolerance in triticale
The Journal of Agricultural Science, 1999Root re-growth, following aluminium (Al) stress, has been used as an indicator of Al stress tolerance. Genetic variation in root re-growth characteristics among eight triticale genotypes was investigated by a diallel analysis. Highly significant variation due to both general combining ability (GCA) effects and specific combining ability (SCA ...

Yield Genes, Heterosis and Combining Ability
The American Naturalist, 1946A WIDE collection of varieties of almost any crop plant often exhibits a wide range in variability for each quantitative character. Yield and other quantitative characters usually are the end result of the interaction of a large number of genes under particular environmental conditions.

Segregation and Combining Ability
1979We have seen in Chapter 1 that with a knowledge of the mendelian principle of units of inheritance and a chequerboard diagram it is possible to work out expected segregations. The technique can be used by the breeder to forecast the numbers of individuals of different types in a family from a deliberate cross and also, in the reverse way, by observing ...

Combining Ability of Waterlogging Tolerance in Barley
Crop Science, 2007ABSTRACTWaterlogging tolerance is one of the major objectives in barley (Hordeum vulgare L.) breeding programs. To make the selection more efficient, an understanding of the genetic behavior of waterlogging tolerance in barley is needed. For this purpose, a 6 by 6 half diallel analysis was conducted in barley from crosses of three waterlogging tolerant

COMBINING ABILITY ANALYSIS IN THE CULTIVATED STRAWBERRY
Canadian Journal of Plant Science, 1971General and specific combining abilities were analyzed for total, marketable, early, and late yield, and for flower stalk number in a diallel cross of eight strawberry cultivars. Data were recorded from individual seedlings restricted to two runner plants, thereby eliminating variability resulting from differences in plant density. General and specific

Combining Ability for Protein Degradability in Alfalfa
Crop Science, 1997The protein in alfalfa (Medicago sativa L.) forage is degraded extensively and quickly by ruminant animals, and N may be lost through NH3 formation. Recent research has indicated that the degradability of forage protein varies among plants. The objective of this study was to determine the relative importance of additive and nonadditive genetic effects ...

Combining ability for breadmaking quality in wheat
Canadian Journal of Plant Science, 1992Combining ability and heterotic patterns for grain yield, kernel weight, and seven traits related to breadmaking quality were determined in 45 F1 hybrid wheats and 18 parents grown in two environments in Italy. Significant, positive general combining ability (GCA) effects were observed for yield (cultivars Pandas and SK 7), protein content (Salmone ...

Heterosis and combining ability in Phaseolus aureus roxb
Theoretical and Applied Genetics, 1974Heterosis and combining ability were estimated in F 1, F 2, F 3 and backcross generations of diallel cross in Phaseolus aureus. Hybrid vigour for yield compared with the mid-parent and better parent was noted in 21 and 20 F 1 hybrids, respectively. There was an appreciable amount of inbreeding depression in the F 2 and F 3 compared with the F 1 hybrids.

Study of Combining Ability and Heterosis in Coffee
2000Combining ability analysis identifies the parents able to transfer their desirable traits to their descendants. It suggests the best hybrid combination and supplies data on the type of gene action, which controls the different agronomic traits. Combining ability in its most general form refers to the behaviour of lines, or cultivars when crossed in ...
