Genetics of sexuality and population genetics of Phellinus weirii

Creator:: Angwin, Peter A.
Abstract:: Phellinus weirii (Murr.) Gilbertson, cause of laminated root and butt rot, is a heterothallic basidiomycete lacking clamp connections. Two biological species groups of the fungus have been hypothesized, the Douglas-fir and cedar-types, on the basis of physiological, morphological and epidemiological differences. Single-spore and vegetative isolates differ in cultural morphology, nuclear...

Correlations between horticultural characteristics and Fusarium root-rot resistance in Phaseolus vulgaris L.

Creator:: Wang, Theodora
Abstract:: To study the association between Fusarium root-rot resistance (Fusarium solani f. sp. phaseoli) and economically inportant characteristics of beans, 2259 lines each consisting of 30 plants were used. The lines were randomly selected for root-rot reaction, but were selected for differences in vigor and differences in plant and seed pigments,...

Inheritance of resistance to Fusarium root rot in Phaseolus vulgaris L., and Phaseolus coccineus L.

Creator:: Azzam, Hassan Ahmed
Abstract:: Progenies of two bean crosses were studied for inheritance of resistance to dry root rot caused by Fusarium solani f. phaseoli. O.S.C. 22 (P. vulgaris) was used in both crosses as the susceptible parent. A Mexican line (P. vulgaris) and a line 2014 of the runner bean (P. coccineus) were...

Soil organic matter management and root health

Creator:: Darby, Heather
Abstract:: Annual applications of fresh or composted dairy manure were assessed for their effects on root rots of sweet corn and snap bean and damping-off of cucumber in a field soil. Soil biological and physical properties were measured as possible indicators of root rot suppressive potential. Regardless of amendment type or...

Forecasting Pseudocercosporella herpotrichoides foot rot of winter wheat

Creator:: Grybauskas, Arvydas P.
Abstract:: The use of fungicides for the control of foot rot of winter wheat, caused by Pseudocercosporella herpotrichoides (Fron) Dei., requires a forecast of disease risk to optimize this management practice ecologically and economically. Foot rot occurs in both the mild, wet (100+ cm, ppt./year) annual cropped areas in western Oregon,...
