TRAITS INHERITANCE AND CLUSTER ANALYSIS OF F1 PLANTS OBTAINED ON THE BASIS OF HYBRIDIZATION OF G.BARBADENSE L.VARIETIES AND LINES

This article outlines the results of analysis of farm-valuable traits inheritance of F1 plants obtained on the basis of hybridization of varieties and lines belong to G.barbadense L.cotton plant species. Dominating level and its inheritance was determined to be under positive and medium negative, dominant and super dominant forms according to the studied cotton weight, fiber length and yield, weight of 1000 cotton seeds in one cotton boll. It is required to continue genetic-breeding research work on next generations for maintaining positive heterosis status achieved at F1 generation. In order to identify the interrelation of varieties by their farm-valuable traits through analyzing group division of clusters in which varieties are combined, a four-cluster type analysis was found to be the most favorable for an effective work. KEY WORDS: species, variety, line, hybridization,inheritance, cluster,generation, cotton weight, fiber length and yield, weight of 1000 cotton seeds in one cotton boll, dominating level, super dominant, heterosis, negative heterosis.
