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 ...

Heterosis and Combining Ability in Wheat

Madras Agricultural Journal, 1977
The magnitude and nature of heterosis and combining ability in a set of diallel crosses of wheat (Triticum aestivum L. om Theil.). involving five genotypes, were studied for grain yield, 100-kernel weight, spike number and plant height. Positive overall heterosis was observed for all the characters except for 100-kernel weight.

Segregation and Combining Ability

1979
We 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 estimates in groundnut

Madras Agricultural Journal, 2000
Accurate identification of promising parents is crucial for groundnut (Arachis hypogaea L.) cultivar development. Six cultivars, namely, ICGS 44, Ginar 1, ALR 2, JL 24, GG 2 and CO 2 were intermated in all possible combinations in a full diallel mating design. The 30 reciprocal F, hybrids and six parents were utilized for the study. Five traits, namely,

COMBINING ABILITY IN WINTER SORGHUM

Madras Agricultural Journal, 1996
The nature of gene action through combining ability analysis for grain yield and its components was studied in 5 X 5 diallel cross of sorghum. Estimates of gea and sca indicated the influence of both additive and non additive gene action for the inheritance of grain yield, stem girth and plant height.

Heterosis and combining ability in Phaseolus aureus roxb

Theoretical and Applied Genetics, 1974
Heterosis 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.

Combining ability studies in tomato (Lycopersicon esculentum Mill.)

Theoretical and Applied Genetics, 1974
Diallel analysis was carried out involving eight diverse varieties of tomato, namely Pusa Early Dwarf, Sl-1, S-12, Punjab Tropics, Sl-120, HS-101, Pusa Ruby and Sl-73-1, to characterize the gene action involved in the inheritance of some of the quantitative traits and to correlate array mean and per se performance with general combining ability (gca ...
