Assesment of salt tolerance of a collection of sorghum genotypes
The area of solonetzes in the Central Ciscaucasia is 1.5 million hectares. Salinity of the soil is one of the main abiotic stresses that do reduce agricultural productivity. Laboratory methods determined the level of salt tolerance in 81 new varieties, lines, hybrids of sorghum and sorghum-sudank co...
