WATER STRESS TOLERANCE IN HYBRID RICE (Pages : 1 - 3)

Climate changes are causing frequent and severe droughts. Such circumstances emphasize the need to understand the response of plants to drought stress, especially in rice, one of the most important grain crops. Therefore, a pot experiment was carried out in Aman season at Bangladesh Institute of Nuclear Agriculture, Bangladesh under drought to find out drought tolerant rice genotypes based on yield and yield attributes. Three treatments (40, 60 and 100% FC) were imposed on five hybrid rice (Dhanigold, BRRI Hybrid-6, Binadhan-7, Agrodhan-12 and Arize-7006) at booting stage and continued to maturity where data on yield and yield attributes were recorded. Growth and yield attributes were significantly (P>0.05) decreased at both 40 and 60% FC. At 40 and 60% FC, drought tolerance mechanism(s) was done based on effective tillers plant-1, filled and unfilled grains panicle-1, 1000-grain weight, yield and total dry matter plant-1. The rice genotypes Arize-7006 and Dhanigold showed less reduction in yield and yield attributes compared to other genotypes. Therefore, based on yield and yield attributes Arize-7006 and Dhanigold showed tolerance in compare to other genotypes.Download
