Screening of cowpea germplasm for field tolerance against biotic and abiotic stresses

Published on

The experimental materials comprising 1100 germplasm
accessions of indigenous and exotic origin were
systematically evaluated during 1996-2003 at the
Division of Genetics, Indian Agricultural Research
Institute, New Delhi. The exotic materials were received
primarily from the International Institute of Tropical
Agriculture, Kano Station, Nigeria. These materials were
also grown in phased manner at hot spots and screened
against diseases such as web blight, Cercospora leaf
spot at H.P.K.V.V., Regional Station, Dhaula Kuan, H.P.,
powdery mildew, YMV at IARI Regional Station,
Dharwad and YMV at GBPUA&T, Pantnagar. Each
entry was grown in a single now plot of 2.5 m length
following augmented plot design. Two checks viz., C
152 and V 240 were repeated after every 20th entry.
The row to row distance was maintained at one meter
while distance between the plants within the row was
kept at 10-15 cm. Most of the lines were also evaluated
during summer (April to June) 2003-05 at IARI, New
Delhi for their response to high temperature. However,
the varieties Pusa Komal and V 130 were used as
checks in these experiments. The average survival
under field conditions was considered as criteria for high
temperature tolerance. The observations on various
yield contributing traits including yield per plant and
disease reaction were recorded and analyzed as per
standard procedures.
