Evaluation of some international rice genotypes in red and lateritic areas of West Bengal

The aim of the present investigation was to identify promising rice genotypes from the 115 international rice varieties. The experiments were conducted in Rice Research Station, Bankura, West Bengal using an augmented block design. A field experiment was conducted during Kharif of 2006 and 2007 to assess the yield performance of 115 genetically diverse rice genotypes along with 6 international checks and one local check (Provat), in red and lateritic areas of West Bengal, India. Eight entries namely, WAB 880 SG 27 ( 50% flowering 98 days, yield 7500 kg./ha), 450-11-1-P28-1-HB (50% flowering 90 days, yield 6666 kg./ha.), WAB 450-11-1-1-P31-HB (50% flowering 95 days, yield 6111 kg./ha.), WAB 878-6-12-1-1-P1-HB (50% flowering 95 days, yield 5444 kg./ha.), D3 (50% flowering 108 days, yield 5555 kg./ha.), IR 78917-B-6-B-B-B (50% flowering 98 days, yield 5277 kg./ha.), WAB-878-6-37-8-2-P1-HB (50% flowering 98 days, yield 5000 kg./ha.) and B6144E-MR-6 (50% flowering 79 days, yield 4722 kg./ha.) were selected on the basis of yield performance.
