بررسی سازگاری و مقایسه عملکرد ارقام سورگوم دانه ای در شرایط آب و هوایی سیستان و بلوچستان

In order to study of adaptability and yield comparison of 11 grain sorghum varieties a field experiment carried out with four replication in Iranshahr and three in Zabol A Randomized complete Block design was used. Grain sorghum varieties were: Kimia, Peyam, Sepeedeh (KGS9), KGS2, KGS3, KGS4, KGS6, KGS7, KOS8, KGSI0 and Local check. Each cultivar was planted in Four rows with Seven meters Length in a plot. During the growing season, the most important traits such as phenological stages, tiller number per plant, , plant height, panicle length and 1000 mass grain yield evaluated. Results Showed that local check with average 8126 kglha had the highest grain yield and KGS 1 0, KGS4, Kimia , Sepeedeh (KGS9) and KGS3 were located in second level in Iranshahr. In Zabol different between Varieties not significant, but average comparison showed that KGS3, KGS9 and KGS4 varieties had the highest grain yield. Key words: grain sorghum, variety, grain yield.
