Abstract

Five barley varieties, viz. Proctor, Kenya Research, Tumaini, MPYT 169-2Y and Can B35/2, were tested in the field to evaluate their resistance traits to D. flavibasis. Can B35/2 was identified as a moderately resistant variety useful for reference in further work. The varieties were observed to recover their growth after the infestation. Visual growth recovery scores in the field experiments suggested the tolerance type of resistance.

Résumé

Cinq variétés d'orge, á savoir, la Proctor, la Kenya Research, la Tumaini, la MPYT 169-2Y et la Can B35/2 furent testés sur le terrain pour évaluer leurs résistances au D. flavibasis. La Can B35/2 a été identifiee come la variété modérément résistante, référence utile pour des travaux ultérieurs. On a observé que les variétés regagnaient leurs croissances après l'invasion de parasites. Les mesurages visuels de guérison dans les expériences sur le terrain ont suggéré une sorte de tolérance.
