ery originated from the USSR, Spain, Turkey, Iran, Tunisia, USA, Afghanistan,
Ethiopia, India, Morocco and Pakistan.
During 1978/1979, 30 seeds of each entry were supplied to be sown in a single
3-m long row. During the following 2 years sufficient quantity of seed of each
entry was supplied to be sown in 4-m long rows in two replications. The seed of a
susceptible check (ILC 1929) was furnished to be sown after every two test
entries, to serve as a spreader-cum-indicator rows.
The cooperators were advised wherever possible to sow the nursery during the
winter in an endemic area. Debris method of inoculation was suggested and if the
level of infection was insufficient, spraying with a spore suspension prepared
from infected plants was indicated. A 1-9 rating scale of Singh et al. (1981) was
suggested for scoring the lines.
During 1978/79, 13 sets of the nursery were distributed. The results from 5 of
11 locations that returned data were worth considering. During 1979/80, 26 sets
were distributed. The results from 7 of 13 locations that returned data were
worth considering. During 1980/81, 26 sets were distributed and results from six
locations were received.
The results from 1978/79, 1979/80 and 1980/81 tests are presented in Tab. 7,
Tab. 8 and Tab. 9, respectively.
1978/79: Seven lines, namely, ILC 191, 192, 195, 200, 201, 202 and NEC
138-2 were rated resistant (3 rating) at all the five locations. Other promising
lines (5 rating or less across locations) were ILC 182, 183, 194, 482, NEC 2388
NEC 138-1. Only one line, ILC 618, showed a susceptible reaction across locations.
Others showed resistant reactions at some locations and susceptible at
others.
1979/80: Three lines, namely, ILC 191, 202 and 3279 were rated resistant at
all seven locations. Other promising lines were ILC 194, 200, 201, NEC 138-2
and 1256. Ten lines showed a susceptible reaction across locations.
1980/81: Eleven lines, namely, ILC 72, 191, 194, 196, 484, 2380, 2956, 3279,
ICC 1903, 5127 and PCh 15 showed resistant reaction across six locations.
Twelve lines, viz. ILC 182, 183, 200, 201, 202, 2548, NEC 138-2, ICC 2160,
7513, 7514, 7520 and PCh 128 were found promising. None of the lines was
found susceptible across locations.
Syria. On the basis of 3 years testing at two locations, 16 lines, namely, ILC 72,
182, 183, 191, 194, 200, 201, 202, 482, 2380, 2548, 2956, 3279, 77 Ms 73022-2,
PCh 15 and 128 were found resistant. Fourteen lines, viz. ILC 195, 236, 244,
248, NEC 138-2, 1256, G 543, 549, ICC 280, 1903, 2160, 4935, 5127 and 7513
were found promising.
Turkey. Six lines, namely, ILC 191, 200, 201, 202, 2380 and 3279 were found
