Penilaian prestasi hasil dan komponen hasil varieti padi terpilih di Seberang Perai

Abstract

The research was conducted at MARDI Seberang Perai research plot during main-season 2011/2012 and off-season 2012. Varieties such as MR 272, MR 278, MR 283 and MR 284 showed high yield potential as compared to the control varieties namely MR 211, MR 219, MR 253 and MR 263. According to correlation analysis, traits such as flag leaf width (r = 0.36, p = 0.01), percentage filled grain (r = 0.43, p = 0.002) and spikelets number/panicle (r = -0.43, p = 0.002) showed association toward yield potential. As a result, high rate of photosynthesis is depend to high leaf surface area. In addition, low number of spikelets /panicle can enhance the grain filling.
