INHERITANCE OF SALT TOLERANCE OF BARLEY CULTURE (HORDEUM VULGARE L.)
The work is performed on the Dagestan experimental station of VIR N.I.Vavilova. Studied salt tolerance 401 sample barley: 306 - membranous, 95 - hulless varieties. The differentiation of culture on the basis of this taxonomic level is shown. Hullessbarley are more resistant to salt stress than filmy. The phenomenon is probably due to the high rate of growth processes in the initial stage of their development. Their relative territorial isolation, mainly South-East Asia, North-East Africa and mountainous regions of Central Asia, is also noted. Salinity-resistant samples were isolated. Among them, the old and selection, hulless and hulled varieties of different ecological and geographical origin. Studied the nature of inheritance of salt tolerance of barley. The hybridization included varieties from Dagestan: k-15019 (salt-resistant) and k-1034 (unstable). Genetic control of salt tolerance differences between the initial samples is determined by alleles of two dominant genes.
