The plant material used was the parents and selected progenies through a program of recurrent selection for resistance to angular leaf spot
and carioca grain type.

pathogen (Phaeoisariopsis griseola) in southern and eastern Africa.
syringae van Hall) of bean and the incidence of angular leaf spot
of cucumber compared to that on plants grown in nonamended soils or soils amended with batches of paper mill residuals that were not composted (Stone et al., 2003).
(2002) revealed that the cultivar AND 227 has four angular leaf spot
resistance genes designated Phg-[1.sup.a], Phg-[2.sup.2], Phg-[3.sup.2], and Phg-[4.sup.2], Mexico 54 has three (Phg-2, Phg-5 and Phg-6) resistance genes, and MAR 2 has two genes (Phg-4 and Phg-5).
Angular leaf spot

It is tolerant to angular leaf spot

Characteristics of 12 parents used in five bean populations for selection for resistance to bean golden mosaic, bean common mosaic, common bacterial blight, and angular leaf spot
The [F.sub.1]-derived [F.sub.2] families were grown under inoculated conditions and heavy pressure of angular leaf spot
[ALS, caused by Phaeoisariopsis griseola (Sacc.) Ferr.] and CBB at CIAT-Quilichao, Colombia.
Parental line EMP 250 has a small Carioca seed type, indeterminate upright Type II growth habit, tolerance to leafhopper (Empoasca kraemeri Ross & Moore), and resistance to angular leaf spot
[ALS, caused by Phaeoisariopsis griseola (Sacc.) Ferr.] and anthracnose [ANT, caused by Colletotrichum lindemuthianum (Sacc.
When cultivars Algarrobo and 223, both susceptible to angular leaf spot
, were crossed with a resistant cultivar, 0258, a segregation ratio of 3 resistant: 1 susceptible plant was observed, indicating monogenic, dominant resistance (Cardona-Alvarez, 1962).
Angular leaf spot
, caused by Phaeoisariopsis griseola (Sacc.) Ferraris, is one of the major diseases affecting the common bean (Phaseoculture lus vulgaris L.) in Brazil which can lead to severe yield losses.
