Pyramiding transgenes for multiple resistance in rice against bacterial blight, yellow stem borer and sheath blight

Theoretical and Applied Genetics, 2002
Here we describe the development of transgene-pyramided stable elite rice lines resistant to disease and insect pests by conventional crossing of two transgenic parental lines transformed independently with different genes. The Xa21 gene (resistance to bacterial blight), the Bt fusion gene (for insect resistance) and the chitinase gene (for tolerance ...

Leaf and stem blight ofEuphorbia geniculata incited byBipolaris zeicola

Phytoparasitica, 1990
Recently leaf and stem blight disease was observed onEuphorbia geniculata Orteg. The pathogen was isolated in pure culture and identified asCochliobolus carbonum Nelson (anamorph:Bipolaris zeicola (Stout) Shoem. =Helminthosporium carbonum Ullstrup). This is the first record of this fungus causing leaf and stem blight disease onE. geniculata.

SCREENING FOR RESISTANCE TO BOTRYOSPHAERIA STEM BLIGHT AND PHOMOPSIS TWIG BLIGHT IN BLUEBERRY

Acta Horticulturae, 2006
Stem diseases of blueberry ( Vaccinium spp.) can cause significant crop loss as well as loss of entire bushes. Stem diseases also tend to be more difficult to control with fungicides than foliar or fruit diseases. We have initiated a program to screen blueberry cultivars for resistance to two important stem diseases, Botryosphaeria stem blight and ...

Gummy stem blight resistance of cucumbers (Cucumis sativus L.)

Euphytica, 1978
A start was made with breeding for resistance to gummy stem blight in cucumber. A method has been development for screening plants in a young stage. Using this method a distinct level of resistance was found in plants of Leningradsky, Wjarnikovsky,a P.I. entry from Birma, Rheinische Vorgebirge and a P.I.entry from Turkey.

OBSERVATIONS ON STEM CANKER AND POD AND STEM BLIGHT OF SOYBEANS IN ONTARIO

Canadian Journal of Botany, 1956
Stem canker caused by Diaporthe phaseolorum (Cke. & Ell.) Sacc. var. caulivora Athow & Caldwell is a serious disease of soybeans in Ontario. Artificial inoculation experiments have indicated (a) that soybeans which are highly susceptible to infection at midstage in their development become progressively less so as they approach maturity, (b ...

Fungi Associated with Leaf and Stem Blight of Vanilla

Journal of Agricultural Research and Development, 2009
The study was carried out to isolate and identify fungi associated with leaf and stem blight of vanilla. The pathogens were isolated from the symptoms expressed on leaves and stem by direct tissue transplanting technique. Result showed that leaf blight was mainly associated with Colletotrichum gloeosporioides, Phytophthora sp., Curvularia lunata, and ...

Resistance to Phomopsis stem blight reduces the lupinosis toxicity of narrow-leafed lupin stems

Australian Journal of Experimental Agriculture, 1988
To determine if resistance to Phomopsis stem blight reduced the lupinosis toxicity of stems in sheep, we tested mature, dry stems of several selected lines of Lupinus angustifolius L. (narrow-leafed lupin). Resistance was defined as a significant reduction in Phomopsis stem blight symptoms on mature, dry stems compared with susceptible cultivars.

Temporal and spatial dynamics of watermelon gummy stem blight epidemics

European Journal of Plant Pathology, 2010
The effect of the distance of initial inoculum on the intensity of watermelon gummy stem blight, caused by Didymella bryoniae, was studied in a naturally-infected rainfed commercial field. The shorter the distance from the focus, the sooner was disease onset and the earlier maximum disease levels were achieved.
