of the world. Due to lack of awareness, the farmers do not distinguish the seed
from grain and hence the quality of farmers saved seed remains below standard.
This seed carries microflora which play an important role in reducing the seed
viability. Among seed microflora, fungal load on the seed is very important.
In this study, seed samples of different varieties of paddy were collected from
farmers in different villages of Haryana from 2002 to 2012. The seed was subjected
to seed health test by blotter technique and observed under stereo-binocular
microscope to assess its fungal load. The per cent germination and vigour index
were also evaluated by paper towel method. A total of 30 fungi belonging to
different groups were recorded from the samples of farmers
saved seed. Alternaria padwickii (28.52%), Curvularia lunata (22.67%),
Alternaria alternata (10.51%), Rhizopus stolonifer (8.96%), Aspergillus
flavus (8.26%) and Fusarium moniliforme (7.15%) were recorded as
major fungi associated with the seed. However, in breeder seed of different
paddy varieties grown at this station, only 22 fungal species belonging to different
groups were recorded. Out of which Alternaria padwickii (10.62%),
Curvularia lunata (7.35%), Alternaria alternata (6.54%), Aspergillus
flavus (6.07%) and Rhizopus stolonifer (5.21%) were recorded as the
major fungi associated with this seed. Average per cent germination and vigour
of farmers saved seed of different
paddy varieties was significantly lower than the breeder seed of different varieties
of paddy grown at this station.]]>Abdul-Baki, A.A. and J.D. Anderson,197313630633Abdulsalaam, S. and K.C.
