“…Heritability estimates obtained in the present study revealed that the traits test weight, flour yield, grain protein, flour protein, colour grade and particle size index were highly heritable, while the traits baking score and baking volume were moderately heritable. The heritabilities are in close agreement with those reported by BAKER et al (1971), DAVIS et al (1961 and EVERSON & SEEBORG (1958). Heritabilities reported for most of the important quality traits, in general, suggest that the inheritance of quality characters may be more simple than was formerly supposed as also observed by HEVNE & S~ITrI (1967).…”

Three sets of hard spring wheats (Triticum aestivum L.) comprising commercial cultivars and advanced generation breeding lines were studied in six different environments, to determine the genotype x environment interactions, heritabilities and correlations among nine quality traits in wheat. Significant genotype × environment interactions indicated that the bread making quality evaluations must be undertaken for several environments. Among the quality traits considered, test weight, flour yield, grain and flour proteins and particle size index were highly heritable. Baking score and baking volume indicated moderate heritabilities. Significant positive correlations existed between protein content (grain and flour) and baking traits, between grain protein and flour protein, and between baking score and baking volume. Flour yield and particle size index were found to be negatively correlated. Implications of these findings on wheat breeding procedures are discussed.

“…Other studies (HAUNOLD, 1960;HALLORAN, 1975b) have indicated the likelihood of protein content being under the control of only a few G. M. HALLORAN major genes and an undetermined number of modifiers. Dominance of low protein content has been reported (CLARK (~ QUISENBERRY, 1929;CLARK et al, 1928) and by other workers partial dominance (DAVIS et al, 1961 ;JOHNSON et al, 1973;HALLORAN, 1975a). Using intervarietal chromosome substitution lines of the cultivar Thatcher in Chinese Spring, KUSPIRA (~ UNRAU (1957) located five chromosomes of 'Hope', each of which increased grain protein content of normal 'Chinese Spring'.…”

The 21 intervarietal chromosome substitution lines of the cultivar Hope in Chinese Spring were used to analyse the genetic differences between the two cultivars Hope and Chinese Spring in grain protein content and grain weight.Only one chromosome of 'Hope, 5D', significantly influenced grain protein content of'Chinese Spring'. Its influence was of only minor effect and was to decrease protein content expression of 'Chinese Spring'. It has been postulated that the genetic control of protein content, in this instance, is most likely due to many genes each of small effect.Five chromosomes of 'Hope' influenced the 1000 grain weight value of normal 'Chinese Spring', all increasing its expression. Chromosomes 1A, 4A and 5B were of major effect and 3A and 6A of comparatively minor effect. A minimal estimate of five genes determines the difference in grain size between these cultivars. The possible evolutionary significance of the contribution of the A genome of bread wheat to grain size determination is discussed. On the basis of certain findings of this study, proposals are made for breeding for increased grain size in hexaploid wheat.

“…Other worlters have related Large dominance variances to other biases such as !inkage disequilibrium (Robertson, 1962;Comstoclc and Robinson, 1948), genotype-environment interaction (Comstoclt and Moll, 1963) and epistasis (Grafius, 1959). Recent investigations using hexaploid wheats by Kronstad and Foote (1964) and Davis et al (1961) all support the over-riding importance of the additive component of genetic variance. In T. d z~n~7 7 1 , Cellis (1961) found a positive relationship between the magnitude of heritability estimates and parental diversity for heading date and plant height.…”

Four lines of Triticum durum, representing diverse levels of genetic relationship and geographic origin, were crossed to produce six segregating populations. Additive and dominance components of genetic variance were estimated for five metric characters in the F2 and F4 generations grown in separate years. Dominance variance predominated in two out of the six populations in F2, but was minimal in the F4 generation. Additive genetic variance generally constituted the major source of genetic variance and was significantly greater than zero in all populations for every character investigated in F4. Populations based on crosses involving either of the two Ethiopian selections with either of the two North American varieties used as parents, in general showed larger amounts of genetic variance than the comparable intercross of the two North American varieties. Considerable genetic variance also existed in the populations derived from intercrossing the two Ethiopian wheats. The results of the investigation tend to support the hypothesized increase in genetic variance associated with genetic diversity, and the preponderance of additive genetic variance in naturally self-fertilizing species.
