| Abstract: |
Spring season rice is one option for increasing the yield under irrigated condition. This yield advantage can contribute considerably
to food security and alleviate poverty in the country. Therefore, varietal improvement works in spring season rice were performed
with aim to identify superior high yielding genotypes suited for double rice patterns. The tested genotypes; WAT-311 (4681kglha),
ZHEF-4 (4230 kg/ha), lET 3137 (4012 kglha), and IDSA-13 (4575 kglha) were found promising in respect of grain yield as well as
earliness in NRSON during 2004/05. During 2005/06, genotypes; OM1271 (5108 kg/ha), WAT 316 (5050 kglha), Judi 503 (50QO
kglha), Judi 141F (4891 Kglha), Judi 541 (4673 kg/ha) and ZHEF-4 (4239 kglha) produced higher grain yield with earliness in
NRSON. All the tested entries in lET, CVT and CFFT had highly significant differences in days to heading, days to maturity, tillers
1m2, plant height, panicle length, filled grains/panicle, unfilled grains/panicle, 1000 grain weight and grain yield at across the
locations during 2004/05-2005/06. Among the tested genotypes; WAT-307 (5125 kg/ha), WAT-316 (3737 kglha), IR 704213-
169(3797kglha), BAGHIXlANG (3786 kglha) and lET 13942 (3899 kglha), were high yielder in lET during 2004/05. Similarly,
genotypes; lET 12703 (5309.3 kglha), C3442-8-1 (4709.3 kglha), WAT 316 (4739.6 kglha), H-3798 (4860.3 kglha) ZHONG00-
126 (4679.0 kglha), OMCS 96 (4528.3 kglha) and RP 1897-23-154 (4389.0 kglha) gave higher grain yield in lET during 2005/06.
During 2004/05, genotypes; NR 1862-3-1-3-1 (5750.0 kglha), IR 274-11-2-1 (4583.0 kg/ha) and IR 71604-4-3-4 (4500.0 kglha)
were found promising in CVT at RARS, Lumle. While Judi 572 (4018 kglha), IR 738381-19-1-5 (3814 kyha), NR 1862-3-1-3-1
(3930 kglha), and NR 274-11-2-1 (3699.0 kglha) gave higher grain yield in CVT at NRRP, Hardinath during 2004105. Among the
tested genotypes; IR 71604-4-3-4 (4363.0 kglha), IR 73838-19-1-5 (3970 kglha) Judi 572 (3856.6 kg/ha) and Gautam (36o3.3 kglha)
produced higher grain yield in CVT at LIBIRD, Chitwan during 2004/05. Whereas, genotypes; NR 274-11-1-2-1 (4687.0 kglha) Judi
572 (4109 kglha), IR 73838-19-1 (4200.0 kglha) BAGHIXIYIANG (3962.3 kglha) and WAT 307 (3901.0 kglha). showed higher
grain yield in CVT at NRRP Hardinath during 2005/06. During 2005/06, genotypes; OMCs97 (4100.0kglha), Judi 721(4300.0kglha),
BAGHIXIANG (3833.0kg/ha), and IR 70423-169(4500.0kglha) were high grain yielder in CVT at JRP, Itahari. Among them, NR
274-10 and IR 57893-10 were found promising for higher grain yield and earliness suited for double rice patterns across the
locations in CFFT during 2004/05-2005/06. |
