Multiplicative vs. arbitrary gene action in heterosis.
In this article we investigate multiplicative effects between genes in relation to heterosis. The extensive literature on heterosis due to multiplicative effects between characters is reviewed, as is earlier work on the genetic description of heterosis. A two-locus diallelic model of arbitrary gene action is used to derive linear parameters for two multiplicative models. With multiplicative act...

متن کاملCharacterization of chitinase activity and gene expression in muskmelon seeds
Chitinase is often produced in higher plants as a general defence response after wounding or pathogenic attack. Since germinating seeds are exposed to soil pathogens, the activity and expression of chitinase in muskmelon (Cucumis melo L.) seeds was investigated. One acidic and three basic chitinase isoforms were detected, beginning 40 d after anthesis in developing and fully mature seeds. Both ...
متن کاملGene Action, Combining Ability, Genetic Expression of Heterosis and Characterization of Rice (Oryza sativa L.) Genotypes for Quality Traits
Present investigation was conducted to estimate the per se performance, combining ability and heterosis for grain quality traits in rice using line × tester mating design. Analysis of variance with respect to crosses revealed significant differences for all the traits studied. GCA and SCA results revealed the predominance of SCA variance in relation to GCA variance for all the traits. For aroma...
متن کاملCombining Ability, Gene Action and Heterosis in Some Inbred Lines of Maize at Two Sowing Dates Using Factorial Mating Design
Combining ability, gene action and heterosis was studied for no. of days to 50% tasseling, no. of days to 50% silking, flag leaf area, plant height, no. of rows/ear, no. of grains/row, 300-grain weight and grain yield/plant in a Factorial Mating in Randomized Completely Randomized Design conducted separately in spring and autumn sowing dates, 2013 through hybridization between three parents of ...
