Determined Of the Phylogenetic Relationships the Intergenomic (?, ?, G) of the Cotton Species

Sirojidinov B. A. | Abdullaev A. A.

Abstract: In this article was analyzed the different species of G. arboreum L. and Australian wild cotton, which used as the research object. The main part of studied cotton species have the difficult hybridization process between itself was determined and showed that they have comparatively distant phylogenetic relationships. The received results by hybridization between cotton species showed that the morphological characters of F1 plants were in the interval condition. Sometimes, the analyzed hybrid plant by the morphologic notes shows that it has familiar to parent plants, specially it is much closer to mother plants. F1 ssp. obtusifolium G. australe, ssp. obtusifolium G. bickii, ssp. perenne G. nelsonii, G. australe ssp. neglectum f. sanginium, F1 hybrid combination were without generation. There were no any growing of bolls and in hybrid combinations the viability of pollen grain showed 0, 0 %. As such as hybridization between G. arboreum L. species and Australian cotton species in a morphological comparative, by learning the result of genetic morphological characters of genetic F1, by using the white fiber of subspecies ssp. nanking was chosen as the mother plant. It was familiar to G. nelsonii wild species.
