“…When the leaf symptoms are evaluated, varieties resistant to wilt disease were Ergenekon F1 and Bafra F1, while Sera Demre-8 was determined as a susceptible variety. According to the browning symptoms of the stem cut, while the resistant variety was Ergenekon F1, Sena was determined as the sensitive variety (Coşkun et al, 2021).…”

Pepper (Capsicum spp.) is one of the major vegetable crops grown worldwide largely appreciated for its economic importance and nutritional value. The aim of study is to be assessing the G2P-Sol pepper core collection including 414 accessions from four cultivated Capsicum species to Verticillium dahliae Kleb. infestation. The use isolates VdCa13, VdCa15, VdCa17, VdCa18, VdCa19 and VdCa21, originally isolated from Capsicum annuum in the Plovdiv region, were used for inoculum. The strongest manifestation of the disease is found in accession GPC 118230 (88.54%). Among the evaluated tested accessions, 85 do not show any symptom of the disease. The average degree of attack by V. dahliae Kleb. is the highest in C. frutescens - 25.70%, and the lowest in C. chinense - 13.62%. The maximum attack index is reported in C. annuum - 89.58%, while C. annuum, C. baccatum and C. chinense all have a lack of infection. The standard deviation varied from 8.54 to 17.60. The coefficient of variation is the highest in C. annuum (106.25%), and the weakest in C. frutescens (39.08%). The percentage distribution of the tested accessions according the attack index of all examined materials is as follows: C. annuum represented 94.43%, C. baccatum - 1.77%, C. chinense - 2.78% and C. frutescens - 1.01%.

“…V. dahliae, a soil-borne fungus, is responsible for more than half of all crop losses. The disease affects the quality and quantity and can even kill the whole plant (Bletsos et al, 2003;Coşkun et al, 2021).…”

The effectiveness of Clonostachys rosea against Verticillium wilt (Verticillium dahliae) and early blight (Alternaria solani) diseases, as the two most important problems in tomato cultivation with significant economic losses, was determined. It was determined that C. rosea was effective on A. solani and V. dahliae and suppressed mycelial growth. Also, the C. rosea on wheat grains inoculated to plants at 20 g, 30 g, and 40 g concentrations before and after pathogens inoculation. Then, fungal discs (2 mm in diameter) from V. dahliae growing colonies were inoculated on the host plant root zone. A. solani was also inoculated (1x106 conidia ml-1) by spraying the foliar parts of the plants. Results showed that V. dahliae caused 76.0% disease severity in control plants, while the disease severity indices were 58.3%, 55.3%, and 25.3% at 20 g, 30 g, and 40 g C. rosea application, respectively. In A. solani x C. rosea treatments, the disease severities were determined as 96.6%, 63.3%, 43.6% and 46.6% in control, 20 g, 30 g, and 40 g application of C. rosea, respectively. The pathogen suppression rates by C. rosea at 30g application dose was 54.8% against A. solani and at 40 g application dose was 66.6% against V. dahliae. The effects of C. rosea on plant growth parameters were also determined. Results showed that C. rosea had a positive effect on the morphological parameters in tomato plants.

Capsicum annuum, native to Central America, specifically Mexico, is widely cultivated throughout Türkiye for its unripe green or ripe red fruits, known as "biber" in Turkish. In this study, a comprehensive assessment of morphological diversity, encompassing both quantitative and qualitative traits, was conducted. A total of 48 different genotypes of C. annuum, varying in colour shape, and size, were collected from the Pazar district and villages in Rize in 2014 and stored at +4°C. Planting of these C. annuum seeds occurred in May 2015 in trays filled with a mixture of peat and perlite at a 2:1 ratio under greenhouse conditions. When the seedlings reached the stage of having 4-5 leaves, they were transplanted into the field in June 2015. The data obtained on morphological characteristics were subjected to analysis of variance (ANOVA), principal component analysis, and hierarchical clustering analyses. The first six principal component axes accounted for 79% of the variance among the 48 genotypes. Hierarchical clustering revealed four main clusters, whereas ANOVA revealed significant differences in various morphological characteristics of 48 different genotypes of C. annuum. This study revealed substantial morphological variability within the C. annuum genotypes examined and hence provides valuable insights for geneticists and breeders, enabling the identification of populations with desirable characteristics for future integration into pepper breeding programmes
