| Abstract: |
A number of experiments were carried out to identify high yielding genotypes of rice for river basin, foot and mid hills agro
environments of western hills in 2004. Genotypes of spring rice namely IR 57893-10 (4.6tlha) and NR 1969-51-5-2-6-2 (4.4 tlha)
were found promising for river basin agro-environments. Similarly, NR 10414-34-2-3 (3.8tlha), NR 10439-28-l-l-1(3.6t/ha) and NR
I 0414-25-2 (3.5 tlha) genotypes of normal rice were also found promising for the same agro-environments. Out of the tested
genotypes of normal rice for foothill, NR 1487 and NR 10353-8-2-1(3.8tlha) genotypes were found promising. NR 10395-16-2-2-
1 (5 .1 tlha), BG 1442 (5 .0 tlha and NR I 0353-8-2-1 (4.9tlha) genotypes were found superior for mid hills. A coordinated varietal trial
was also conducted in mid hill agro-environment. The genotype NR 10492-7-2-2 (4.9tlha) and NR 10342-29-2-2 (4.6 tlha) identified
as promising for mid hills. Similar types of experiments were also conducted during 2005. Genotypes namely OR 367, NR 1835-2-
1-2-2-1-4, BR 6158-RWBC2-6-8 and NR 176-6-43-3-3-2-1 were found promising with the average grain yield of 5.0- 5.5 t/ha for
normal irrigated condition of river basin. Whereas, lR 59539-2 (7.8 t/ha), lET 3137 (7.6 t/ha), Radha-4 (7.2 t/ha) and BPI 49F
(5.9tlha) were found promising genotypes for the rainfed condition of the river basin. FRX 30 5F6Bl-8 (5250 kg/Ita) and lR 69745-
251-2-2-1-1 ( 4~ 17 kglha) genotypes of fine and aromatic rice were identified as superior for 1iver basin. Genotypes namely NR
10414-34-2-3 (6.7 tlha), NR 10353-8-2-1 (6.4 tlha) were found promising for mid hills and preferred by the farmers. LR 91006
(5116 kglha) and LR 93015 (4901 kglha) were found promising genotypes for cold tolerance in high hills. Statistically, the
difference in grain yield due to genotypes was found significant. |
