Performance of Different Rice Genotypes in the Cold Climatic Region of Malakand Division

Abstract

An experiment was conducted to evaluate the growth and yield performance of rice genotypes PK3445-3-2, OM5627, IR64, IR8225-9-3-2-3, CIBOGO, Japanese rice and Fakhre Malakand under agro-climatic conditions of Malakand division. The rice genotypes differed significantly with respect to days to 50% flowering, days to maturity, plant height, thousand grain weight and paddy yield (t ha^-1) except panicle length and number of tillers/hill. Japanese rice has smallest panicle length (21.23 cm) and OM5627 has longest panicle length (28.00 cm). In genotypes Fakhre Malakand showed higher paddy yield (9.58 t ha^-1) followed by PK3445-3-2 and IR64 produced paddy yield 8.66 and 8.51 t ha^-1 respectively, while the minimum paddy yield (4.02 t ha^-1) was recorded in Japanese rice. Therefore the advanced rice genotype PK3445-3-2 should be further evaluated on farmers’ field for approval as a commercial variety and to be best fit in the prevailing cropping pattern of the region.
