Оцінка різноманіття робочої колекції батьківських ліній соняшнику за генетичними дистанціями

Abstract

According to the results of the study conducted 100 inbred lines of sun-flower are investigated by RAPD - analysis, at this the level of polymorphism has varied from 33,3 % to 69,2 %. On the basis of the data from RAPD – anal-ysis genetical distances between inbred lines are calculated and the dendrogram is built. By the genetical distances 7 available groups are distinguished, for each group pairs of lines are found. By the results of PCR – analysis the inbred lines with different genetical distances are chosen for crossing between them and hybridic combinations are received
