Heterosis and combining ability effects on cotton. I. Combining ability

Australian Journal of Agricultural Research, 1988
Combining ability for a number of yield and quality attributes of cultivated cotton (Gossypium) was studied in two diallel experiments under high-yielding conditions in northern Australia. The first diallel comprised nine G. hirsutum parents of North American and African origin, the second diallel of thirteen parents besides American and African ...

THE COMBINING ABILITY IN CASTOR

Madras Agricultural Journal, 1995
Combining ability of the three pistillate lines and eight testers was assessed by Line x .ester analysis. The variance components due to sea were higher than gca for five characters except for number of nodes upto the main spike indicating the predominance of non- additive gene action.

Combining Ability in Sorghum

Madras Agricultural Journal, 1979
The nature and magnitude of combining ability effects in 36 crosses of Sorghum involving two male sterile lines with 18 pollinators were studied in respect of yield per plant and other yield contributing charecters. The estimate of variance due to g.c.a.

Combining ability in pigeonpea

Madras Agricultural Journal, 2000
Using combining ability studies line x tester analysis in pigeonpea revealed non-additive gene action for the expression of days to first flowering, days to 50 per cent flowering, number of branches per plant, plant height, number of pods per plant, days to maturity, number of seeds per pod and additive gene action for seed yield.

Combining Ability in Sugarcane

Madras Agricultural Journal, 2009
General and specific combining ability variances and their effects were studied for 18 cross combinations in Line X Tester mating design. The study includes Cane yield and quality characters in sugarcane. Study indicated the predominance of non additive gene action for all the characters studied.Among the lines CoC 671 and Co 86032 were good general ...

COMBINING ABILITY IN GRAIN SORGHUM

Madras Agricultural Journal, 1990
A diallel set of 10 varieties of grain sorghum Sorghum bicolor (L.) Moench was studied to estimate the combining ability for yield and yield contributing traits. The sca variance was higher than gca variance for almost all the characters. Entry M-209 was better general combiner for earliness, GJ-35 for dwarfness, DMYT 231 for panicle length, DR 23, for

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).

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.

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 ...

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
