DISPLAY OF HETEROSIS AT POTATO HYBRIDS (SOLANUM TUBEROSUM L.) IN THE CONDITIONS OF THE MOUNTAIN ZONE OF TAJIKISTAN
Abstract
In the conditions of a mountain area of Tajikistan (Jirgital district, 2700 altitude) by us it is spent interspecies (Solanum tuberosum L.) potato hybridizations at various schemes of crossing. At selection of the parental forms, used in the course of crossing the special attention has been given such economic – to valuable signs, as efficiency, precocity, stability to illnesses and keeping capacity of tubers at storage. The received hybrids of a potato have the best indicators to morphological signs, on growth by development, on formation degree generative bodies, and also on efficiency. The effect heterosis to quantitative signs at hybrids depending on the crossing scheme was a miscellaneous 1000 pieces of the received hybrid seeds, quantity of tubers, weight of one tuber and efficiency at hybrids of a potato are defined true (Htru), hypothetical heterosis (Hhyp) and domination factor (H). The most valuable hybrid combinations for reception of new perspective hybrids, lines, forms and potato clones in selection process are revealed.
