Abstract

The new barley cultivar Negin was derived from cross between Violeta/Mja and Manal/Alanda-01 lines as female and male parents, respectively. Initial cross between parents of this cultivar and selection in segregating populations was performed till pure line stage, in Seed and Plant Improvement Institute. Observational evaluation and preliminary and advanced yield trial were performed at Ahvaz, Darab, Zabol and Gonbad Agricultural Researches Stations and target line was selected because of its high yield and desirable agronomic characteristics. Grain yield stability experiment included line No. 9 (Negin cultivar) and 17 pure lines and Nimrooz/Sahra and Oxin as checks were conducted in Ahvaz, Darab, Zabol, Gonbad and Moghan Agricultural Researches Stations in 2016-2018 cropping seasons. Results of grain yield mean comparisons, rank mean, rank standard deviation and kang’s rank sum were used for selecting of genotypes with high and stable yield. Grain mean yield of line No. 9 (Negin cultivar) was 4480 kgha-1 that was 13.7% more than Oxin with 3939 kgha-1 grain yield. In the research-extension experiments, the grain yield mean of this variety was 4554 kgha-1 that was between 2 to 27% more than controls used in each location. According to the results it was determined that WB-95-9 line in addition to desirable performance and desirable agronomic characteristics, was generally adapted to the warm regions of the country and therefore was released as Negin cultivar. Negin variety is six rows, exhibits lodging resistance and non-shattering rachis. The growth type of this cultivar is spring and its protein content is 10.9%. Negin variety has high tolerance to salinity and drought stresses. Its reaction to powdery mildew is semi-resistant to semi-sensitive and to yellow rust and barley stripe is resistant to semi-resistant.
