Abstract
In recent years climate change is increasing the incidence of both
types of floods and yield loss due to floods ranges from 10 to 100 % depending
on the cultivated variety, flood duration, depth and floodwater conditions. In
recent years due to heavy and intense rainfall and cyclonic storms, paddy crop
is experiencing damage due to flooding. If the flood water stagnation remains
for more than a week the varieties are unable to sustain and there by the yield
levels are drastically reduced. Hence, there is a need to develop submergence
tolerant variety to minimize the yield losses. Acharya NG Ranga Agricultural
University (ANGRAU), Regional Agricultural Research Station, Maruteru has
developed a flood tolerant culture MTU 20601-1-1-1-1 through conventional Plant
Breeding using PLA 1100 and BM 71 as parents from 2008 to 2011. The flood
tolerant rice culture was extensively evaluated for yield in semi deep water
ecosystem at RARS, Maruteru over the years of Kharif, 2012 to Kharif,2016 in
Station yield trials The entry recorded superior grain yield( 4370Kg/ha)
against check PLA 1100(3811Kg/ha) and yield advantage over check was 14.67 The entry
was tested in AICRIP trials from 2014 to 2017 at RARS, Maruteru and the results
revealed that the entry registered 4650Kg/ha and found to be significantly
superior over the national check, Sabitha(3703Kg/ha) and the per cent increase
over check was 25.60. The entry recorded a mean grain yield 4282 Kg/ha and
found to be significantly superior over the national check, Sabitha (2790Kg/ha)
& yield advantage was 1492 Kg/ha and per cent increase over national check
was 53.48 and zonal check Poornendu (1444Kg/ha & 50.88 respectively) in
eight locations of six states of south eastern region. Multi location testing
of the entry from 2015 to 2017 revealed that the entry has out yielded
(5370Kg/ha) and found superior over the best check PLA 1100(4290Kg/ha) and the
per cent increase over check was 25.18. Minikit testing in 890 locations for a
period of three years from 2016 to 2018 revealed that the average mean yield of
the entry over three years was 6039Kg/ha against local popular check PLA
1100(5700Kg/ha) and per cent increase over check was 6.0 when tested in Andhra
Pradesh.
