Regional Agricultural Research Station Nepalgunj during 2011and 2012 rainy seasons to
identifY the yield potential resistant/tolerant to biotic and abiotic stress in Normal. irri~ted
rice, Fine and aromatic rice, Rainfed lowland medium (CVTRLM), Upland nce(direct
seeded system) and Rainfcd lowland early rice. These trials were received from National
Rice Research Program, Hardinath Baninya, Dhanusha 2011and 2012 and develop as
Regional Elite Varietal trial at RARS, Nepalgunj in 2012, Among the tested genotypes, In
CVT on Normal irrigated Rice, IR 81896-B-B-484 was found as highest yielder
(5404kg/ha) followed by IR 80411-B-28-4 (5213), IR 79615-9-3-1-3 (5146lcg/ha) and IR
76479-48-3-1 (5125kg/ha) respectively, In CVTIR.EVT on Fine and Aromatic (FAR ),
IR48725-B-B-99-3 -B-B-99-3 produced highest grain Yieldlha (4192kg/ha) followed by
IR78539-32-l-2-1(2958kg/ha) and IR77542-90-1-1-1-5 (2874kglha) respectively,
Likewise CVTIR.EVT on Rainfed lowland medium(CVTRLM), IR69707-10-1-2-2-3-3
produced highest grain Yieldlha (422lkglha) followed by IR45416-R-R-R-R-156-
2(4052kglha) and IR70213-10-CPA-2-3-2-1 (4008kglha) respectively. Similarly in
CVTIR.EVT on Rainfed lowland early rice, HAROINATH-1 produced highest grain
yieldlha (3190 kglha) followed by IR80436-B-73-3 (3019kg/ha) and IR80412-B-19-1
(3010kg/ha) respectively. In CVTIR.EVT Upland rice (direct seeded), IR 79413-B-362-B-B
produced highest grain yield (3985kglha), followed by IR 78914-B-22-B-B-B (3885kglha)
and GHAIY A -2(ST.CO (3776kglha) respectively. These direct seeding also eliminates the
risk of yield loss due to transplanting delay. These selected genotypes were promoted to
Regional Advance Yield Trial and Regional Farmers Field Trial.
