Abstract :

Part of paddy lands of Dasht-e-Sar region of Amol was irrigated by low salinity (brackish water) Garmroud River. To investigate the effect of Garmroud irrigation water on growth and yield of 9 selected genotypes obtained from the ninth generation (M9), standard cultivar tolerates salinity variety (Fl478), Tarom Mahali, Hassani, Anbarboo and Barekat varieties, a total of 14 genotypes were evaluated in a randomized complete block design (RCB) with three replications in 2020. The experimental farm was located in the village of Shahneh Kalay Dasht-e-Sar Amol (longitude 63ْ 1َ E, latitude 40ْ 30َ N, altitude 75 m). The results showed that the earliest genotypes were lines No. 2310 and 2212 from seed sowing to 50% flowering stage, equal 85 and 88 days. Genotype 133 was the shortest line with a plant height of 124 cm. Traits including number of panicle per hill, panicle length (cm), number of full grains, empty and total grains per panicle, 1000-seed weight (g), were different 15-25, 20-27, 55-112, 91-161, 10-83 and 20-27,  respectively. The yield of genotypes varied between 1500 and 6000 kg/ha. Due to the variety of changes in agronomic traits, 2212, 2310, 133 and Hassani variety were recommended in this area of paddy field
