بررسی وضعیت سازگاری و عملکرد ارقام مختلف برنج در بلوچستان

A field experiment was conducted to study the effect of rice (Oryza sativa) genotypes on grain yield in Nikshahr region. Seven rice genotypes viz., Shafagh, Fajr, Shiroudi, Ghaem and Local Sadri (check) cultivars and 8405 and 843 lines were studied. In each plot, transplanting in 6 rows with 2.5 m was done. MSTAT-C software was used for analysis of data. Result of pooled analysis data of two years showed that Fajr and Shiroudi cultivars similarly produced the highest grain yield with 5498 and 5134 kg ha-1, respectively. Ghaem cultivar with 2839 kg ha-1 grain yield recorded the lowest grain yield. It could be concluded that Fajr and Shiroudi cultivars are permissible for higher productivity of rice in Nikshahr region. . Key words: Rice genotypes, grain yield, second seasons.
