بررسی میزان آلودگی لاین‌های جدیدکنجد به بیماری گل سبزی و بوته میری در استان بوشهر

This study was carried out to evaluate the infection levels of phyllody and damp off (Fusarium oxysporum) diseases in sesame (Sesamum indicum) new lines and achieve superior sesame varieties for cultivation development in Bushehr province. In this regard, 9 lines were selected from the preliminary experiments along with two control varieties national and regional (Shevin and Dashtestan2) totaling 11 experimental treatments that were cultivated in a complete randomized block design with three replications in Borazjan region Bushehr province in the year 1402 for comparison. Based on the results, Among the genotypes studied in this experiment, a statistically significant difference was observed in the incidence of phyllody and damping-off diseases; so genotype 9 had the highest damping-off incidence at 7.3%, a 7% increase compared to the local control treatment (Dashtestan2). Treatments 1, 2, and 3 exhibited the lowest percentage of damping off, which were not significantly different from the control (Shevin and Dashtestan2). On the other hand, the highest percentage of phyllody disease infection was observed in genotype 5 with an average of 10.3%, which had a 6.3% increase compared to the local control treatment (Dashtestan2). The lowest percentage of phyllody disease infection (3.3, 3.3, and 4.3) was observed in genotypes 1, 2, and 4, being in the same statistical group as the control cultivars (Shevin and Dashtestan2). According to the obtained results, it appears that genotypes No. 1 and 2 displayed the lowest infection rates of both phyllody and damping-off diseases, in the Borazjan region, suggesting that these lines are less vulnerable to the disease. These varieties under investigation exhibit superior performance to the diseases studied in this region.
