Testers and Combining Ability

2010
The inbred–hybrid concept was created in the public sector with the direct influence of Darwin, Festetics, Mendel, and Vilmorin. East related those biological principles to the more practical plant improvement studies to achieve his goals (Hayes, 1956).

Model6: Combination of Both Abilities

2010
The existence of both basic dimensions, distance or the ability to love spatially and control or the ability to regulate oneself temporally, is fundamental to understanding all the other forthcoming models of relational competence theory (RCT). How we approach or avoid another individual, activity, object, or task and how fast or how slowly this ...

COMBINING ABILITY STUDIES IN GROUNDNUT

Madras Agricultural Journal, 1996
Five rust resistant and four rust susceptible groundnut (Arachis hypogaca L.) genotypes were crossed in all possible combinations to study the nature of combining ability and gene action involved for 13 quantitative traits. Combining ability analysis showed the importance of GCA variance alone for number of primary branches and days to 50 per cent ...

COMBINING ABILITY IN RICE

Madras Agricultural Journal, 1990
In rice, the variances of specific combining ability were higher than general combining ability for plant height, panicle length and grain yield per plant which indicated non additive gene action. The genotypes ADT 31 and Utrirajappan were found to be good general combiners for grain yield and their cross involving these two parents showed high sca ...

Yield Genes, Heterosis and Combining Ability

The American Naturalist, 1946
A 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.

Principles for Griffing's combining ability analysis

Genetica, 1993
Griffing'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 IN FODDER LABLAB

Madras Agricultural Journal, 1996
Combining ability analysis was done in six genotypes of fodder lab lab for 12 traits viz plant height, primary branches per plant, secondary branches per plant, number of leaves, specific leaf weight, green fodder yield, dry weight of leaf, dry weight of stem, leaf:stem ratio, dry matter yield, crude protein and phosphorus content. Based on gea effects

COMBINING ABILITY IN FODDER PEARL MILLET

Madras Agricultural Journal, 1996
Combining ability analysis was done in pearl millet for 12 quantitative traits including crude protein, calcium and oxalate contents. Predominance of GCA variance was observed in the traits viz, days to 50 per cent flowering, intermodal length, green fodder yield per clump, dry matter yield per clump, crude protein and oxalate contents while other six ...

COMBINING ABILITY IN BARLEY BREEDING

Madras Agricultural Journal, 1983
Combining ability was studied for grain yield and its component using the F1, F and F, of a 6 x 6 diallel set in barley. Both GCA and SCA variances were significant for all the traits in each generation. The GCA effects were associated with per se performance of parents for almost all the traits, ayoti, DL 70 and PL 102 were found to be good general ...

Combining ability in early Indian cauliflower

The Journal of Agricultural Science, 1977
SummarySix early maturing inbreds from maturity group I of Indian cauliflowers were selected and diallol crosses were made to study the combining ability of inbreds and identify the desirable parent(s) for hybridization. Seven characters, i.e. curd weight, curd size index, maturity, plant height, number of leaves, leaf size index and plant spread were ...
