“…ALS was evaluated based on the natural occurrence of the disease in the field, using a grading scale modified by Inglis et al (1988). This scale ranges from 1 to 9 in the following manner: 1, plants without any symptoms of disease; 3, presence of lesions on 5 to 10% of the foliar area, without sporulation of the pathogen; 5, presence of lesions on more than 20% of the foliar area and presence of several sporulated lesions; 7, presence of lesions on more than 60% of the foliar area with symptoms of chlorosis and necrosis; 9, lesions on 90% of the foliar area, frequently associated with defoliation and plant death.…”

ABSTRACT. In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a partial diallel in a 5 x 7 scheme. Group 1 was composed of parents with black grains and erect plant architecture, while group 2 was composed of parents that had carioca grains and were resistant to the main fungal diseases that occur in the common bean. The following traits were evaluated: severity of angular leaf spot (ALS), plant architecture (PAG), and grain yield (YIELD). The data were analyzed according to a partial diallel model using parents and F 1 hybrids. In the genetic control of ALS and PAG, additive effects were predominant, while for YIELD, additive effects were predominant in one season and dominance effects were in another season, because it is a more complex trait than ALS and PAG. For YIELD, we observed an interaction between general combining ability and specific combining ability between seasons. The genes that control ALS, PAG, and YIELD were in eight of the 12 parents evaluated in the diallel. The cultivar 'BRS Estilo' is suitable to use as a parent in common bean breeding in terms of ALS, PAG and YIELD. Recurrent selection is the most recommended option for simultaneously breeding for PAG, YIELD, and resistance to angular leaf spot in bean culture.

“…of leaves examined For assessment of disease intensity, Twenty two accessions of common bean were screened at flowering stage of crop. Observation on angular leaf spot was recorded from flowering till maturity of the crop using Centro International de Agricultura Tropical (CIAT) 1-9 scale adapted from (Inglis et al 1988) and (Razvi et al 2017) which is given in Table 1. x 100…”

An experiment was conducted to identify promising accessions suited for cultivation under cold arid conditions of Leh, Ladakh. Twenty two accessions of French bean were screened for resistance to angular leaf spot disease during the spring seasons of 2016 and 2017 in the Experimental field of High Mountain Arid Agriculture Research Institute (HMAARI) Leh, Ladakh, Sheri Kashmir University of Agricultural Sciences and Technology of Kashmir. The study revealed that under natural epiphytotic conditions none of the accessions was resistant in reaction. Eight accessions viz., Acc-WB22, Acc-1643, Acc-1690, Acc-811, Acc-4564, WB-1247, WB-185 and Acc-252 were moderately susceptible. All other fourteen accessions viz., Acc-966, Acc-335, Acc-1129, Acc-21529, Acc-WB216, Acc-719, WB-956, Acc-622, Acc-1492, Acc-195, Anupama, WB-6, WB-257 and Local exhibited susceptible reaction

Determination of the inoculum sources of angular leaf spot disease caused byPseudocercospora griseola, on common beansPseudocercospora griseola, the causal agent of angular leaf spot, has caused serious damage on local bean genotypes in bean greenhouses in Zonguldak, Bartın, and Karabük provinces of Turkey. The disease begins as angular spots on leaves which are followed by quick death of leaves and it causes deep brown wounds on the seeds. Since bean producers use their domestic seeds, infected seeds increase the inoculum source year by year and distribute the disease to close by provinces. Therefore, determination of the inoculum source of angular leaf spot disease agent, P. griseola on the locally cultivated bean genotypes was aimed. For this purpose, seeds with suspected symptoms of the disease and diseased plant debris were collected from the greenhouses where the disease is seen every year and analyzed in the laboratory in 2013. Then trials were established with the diseased seeds planted in uninfected soil and healthy seeds planted in diseased plant debris mixed with uninfected soil. As a result of the experiments, it was determined that angular leaf spot of beans was carried by seeds and diseased plant debris in the Western Black Sea Region.Keywords: Pseudocercospora griseola, bean, seed, inoculum source ÖZFasulyede köşeli yaprak lekesine neden olan Pseudocercospora griseola ülkemizde Zonguldak, Bartın ve Karabük illerindeki seralarda, yerel fasulye genotiplerinde ciddi zararlara neden olmaktadır.
