| Abstract: |
Irrigated low land is the most productive land and Sabitri is the most dominant variety grown
under irrigated ecosystem . In order to develop irrigated rice varieties for higher grain y ield
with better quality IRRON-I and IRRON-II, IET-N, CVT-N and CFFT-N were studied at
different locations under irrigated condition during 2009-2010. The genotypes : IR 7100-247-
1-1-2, YN 3109-23-1-2, Sabitri, Radha-7, IR 80905-50-1-3-2, IR 21141-24-2 and IR 83326-
39-1-2 were produced higher yield of 5, 5, 4.8, 4.7, 4.6 4.2 and 4 .2 T/ha respectively in
IRRON-I during 2009. Genotypes; PCT6\0\0\0> 19-1-4-3-l-l-1-3-l, OM7938, YEZIN LONE
THWE, OMCS 2007, YN 3109-23-1-2, CT15809-l-2-1-l-2sr-1-2-2-2-M and OM6161 were
found promising in IRRON-I during 2010. Similarly, genotypes; IR80482-64-3-3-3, IR77298-
14-l-2, BATANZPJAMAN, IR79218-43-2-l-2, IR79637-2-3-2-l, IR77480-1-2-3-3,
IR62558-SRN-17 -2-1-3, IR81358-98-1-3 -2-3, IR77499-81-3-I-l-3, IR79253 -98-3-2-3,
IR82786-43-3-2-I and JR82489-612-2-3 -2 were found promising in IIRON-II during 20 I 0.
All genotypes were fotmd s ignificantly different in days to heading, days to maturity, plant
height (em), grain yield t/ha and filled grains/particle in IET under normal irrigated conditions
in 2010. Whereas, panicle length(cm), tiller/m2, unfilled grains/panicle and 100 grain weight
(gm) did not differ among the genotypes in lET under irrigated cond ition in 20 10. All
observed traits were found highly s ignificant different among the genotypes across the
locations except grain yie ld kg/ha at RARS, Nepalgunj , plant height (em) at NMRP, Rampm
and RARS, Tarahara, till ers/m2 at NMRP, Rampm and RARS, Tarahara in CVT-N during
2009. The genotypes: OM-576 (4717 kg/ha ), lR70215-70-CPA-3-4-I-3 (4731kg/ha),
IR72997-159-2-2-I (4672kg/ha), IR77721-93-2-2-1-2 (4700kg/ha ), lR76479-48-3-
1 ( 4517kg/ha ) were found high yielder than check ( Sabitri) 4492kg/ha in CVT -N during
2009. Among them, IR 73006-8-2-2-1, IR 72997-159-2-2-1, IR 73007-13 1-1-2-2, IR 83614-
564-B were produced significantly higher y ield of 3.9, 3 .9, 3.9, 3.8 t/ha respectively over
popular check (Sabitri) that yielded 3.7 t/ha at across the locat ions. The genotype; NR 79-2-1-
3-3-l, IR81896-B-B-3 8 and IR81896-B-B-639 produced significantly higher grain y ield of
4.6, 4.5 and 4.3 t/ha respectively over check genotype Sabitri (2.3 t/ha). In CFFT2009,
genotypes RHS 379-25CX-1 CX-2,9939, BM9855 and Mithila had produced higher grain
yield of 4.7, 4.3 and 3.9 t/ha respectively. IR 72889-69-2-2 produced highest mean gra in yield
(4.65 t/ha) followed by IR 78581 -1-2 (4.30 t/ha) and IR 77721-93 (4. 12 t/ha) in CFFT-N-
