Inheritance, general combining ability and specific combining ability were studied using four parents: FH-901, NIAB-Karishma, CIM-496 and MS-84 for different plant traits in Upland cotton (Gossypium hirsutum L.). Mean values of all genotypes were significantly different from each other for all the traits studied. Epistasis was not found to be involved in any of the traits. The inheritance of all the traits was controlled by additive type of gene action with partial dominance except seed cotton yield that was controlled by over-dominance type of gene action. It was further noticed that the parent MS-84 was best general combiner for the traits like plant height, number of monopodial branches and number of bolls. The cross MS-84 × NIAB-Karishma showed greater specific combining ability for plant height, number of monopodial branches and number of sympodial branches.

Conducted the breeding researches with interspecific cotton crosses are aimed to obtain genotypes have desired fiber characteristics like Gossypium barbadense L. and have high yields potential like Gossypium hirsutum L. In this study, gene action and useful heterosis were investigated for fiber quality and yield traits in interspecific cotton crosses. The 12 F 1 's and their parents were evaluated in a Randomized Complete Block Design with four replications at the Nazilli Cotton Research Institute's fields during 2011 and 2012 cotton growing season. Claudia, Candia, Sahin 2000, BA 308, Naz 07 and Fantom (Gossypium hirsutum L.) were used as a female parents and Giza 45 and Avesto (Gossypium barbadense L.) used as a male parents. Non-additive gene effects for yields, fiber strength and fiber length were greater than additive gene effects. The useful heterosis were positively significant for fiber strength and fiber length. Candia x Giza 45 hybrid was promising hybrid for all observed characters.

“…Complete diallel designs have frequently been used to determine the mode of gene action for agronomic traits in cotton. Using this approach, significant reciprocal effects have been detected for fiber length, fiber strength, fiber elongation and fiber fineness and lint percentage (Shaukat et al, 2013), monopodia branch length (Zangi et al, 2010), days to first flowering, seeds, locule -1 and lint percentage (Khan et al, 2011).…”

Even when conventional breeding was effective in achieving a continuous improvement in yield, Molecular Genetics tools applied in plant breeding contributed to maximize genetic gain. Thus, the use of DNA technology applied in agronomic improvement gave rise to Molecular Breeding, discipline which groups the different breeding strategies where genotypic selection, based on DNA markers, are used in combination with or in replacement of phenotypic selection. These strategies can be listed as: marker-assisted selection; marker-assisted backcrossing; marker assisted recurrent selection; and genomic selection. Strong arguments have been made about the potential advantages that Molecular Breeding brings, although little has been devoted to discussing its feasibility in practical applications. The consequence of the lack of a deep analysis when implementing a strategy of Molecular Breeding is its failure, leading to many undesirable outcomes and discouraging breeders from using the technology. The aim of this work is to trigger a debate about the convenience of the use of Molecular Breeding strategies in a breeding program considering the DNA technology of choice, the complexity of the trait of agronomic interest to be improved, the expected accuracy in the selection, and the demanded resources. Key words: DNA marker, selection, plant improvement.
