Three F8 breeding lines, developed by USUA-ARS and the Washington
State University Experiment Station, were released in June 1983. Each
line combines resistance to several soilborne diseases together with
white flowers, green cotyledons, and dimpled or smooth seed.
'WR-1158' has a semi-fasciated growth habit, with a strong double-
podding tendency. WR-1158 blooms in the 13th node and usually will not
exceed 76 cm in vine length. The dry seeds are slightly dimpled and are
dark green in color. WR-1158 is resistant to races 1, 2, 5, and 6 of
Fusarium oxysporum f. sp. pisi (van Hall) Snyd. & Hans, and is tolerant
to the root rot complex of eastern Washington.
'WR-1167' blooms in the 13th node, is double podded with long
pointed pods, green dimpled seed, and is about 76 cm tall when grown at
Prosser, Washington. WR-1167 is resistant to races 1, 2, 5, and 6 of F.
oxysporum f. sp. pisi and to P. solani f. sp. pisi in both artificially
and naturally infested soil.
'RR-1178' is about 76 cm tall at Prosser, blooms in the 14 to 15th
node, is double podded with long, pointed pods, and produces a mixture
of dimpled and wrinkled, green seed. RR-1178 is resistant to races 1
and 2 of F. oxysporum f. sp. pisi and, in artificially infested soil, it
was significantly more resistant to root rot caused by F. solani f. sp.
pisi than 'Dark Skin Perfection'. RR-1178 was found to be resistant to
root rot in naturally infested soil in New Zealand In L980.
