First testimony of new host plant of Colletotrichum magnum (S.F. Jenkins & Winstead) Rossman & W.C. Allen causing anthracnose in Carica papaya L. fruits in Bali, Indonesia



Anthracnose forms a group of fungal diseases that affect a variety of crop plants in warm and humid areas. Anthracnose causes the wilting, withering, and dying of tissues of plants, commonly infecting the developing shoots, leaves, and fruits. It critically affects the quality and production of Carica papaya fruits in Bali, Indonesia. The pathogenic fungi belonging to the genus Colletotrichum cause anthracnose fungal disease. Research on morphology and molecular identification of pathogenic fungi is very important to determine the type of pathogenic fungus that causes anthracnose disease in the papaya fruit. The latest study aims to identify the pathogen that caused anthracnose on papaya fruits in Bali, Indonesia, carried out during July – December 2021 at the Belok Village, District of Petang, Badung Regency, and in Laboratory of Biochemistry, Udayana University, Badung Regency, Bali, Indonesia. The study used Koch’s postulates to confirm the pathogenicity and continued with macro- and micro-morphological characterization. Based on macro- and micro-morphological characterization, the pathogen has shown similar traits to the genus Colletotrichum. Molecular identification took place using the ITS sequences to increase data robustness. Based on the molecular analysis, the DNA sequences of the genus Colletotrichum isolated from papaya fruits showed the symptoms of anthracnose disease. Based on the latest findings, the pathogen causing anthracnose disease in Carica papaya fruits showed as the species Colletotrichum magnum in Bali, Indonesia.

Keywords: Carica papaya, Colletotrichum magnum, anthracnose, molecular identification

Key findings: The latest study identified the pathogenic fungi (species Colletotrichum magnum) causing anthracnose disease on Carica papaya fruits through morphological and molecular approaches.

Mutation induced by radiation may result in increased variation in Jerusalem artichoke. The objective of this study was to determine the LD50 and effect of gamma rays on growth and tuber yield of two Jerusalem artichoke genotypes HEL 65 and CN 52867. The experimental design was a completely randomized design (CRD) with 4 replications. The results demonstrated that LD50 for the genotypes HEL 65 and CN 52867 were 22 and 27 Grays (Gy), respectively. The radiation treatments did not change flower characters in either genotype. Germination percentage and plant height in both genotypes were decreased by increasing the radiation dose. In contrast, the number of branches was increased with higher gamma radiation doses (20 and 25 Gy). Gamma ray radiation at 5 Gy increased tuber yield in both Jerusalem artichoke genotypes. The present study indicated that gamma radiation might be useful for improvement of important traits such as yield in Jerusalem artichoke.
Key words: Helianthus tuberosus L., irradiation, plant height, fresh tuber yield

Key findings:
The LD50 for Jerusalem artichoke genotypes HEL 65 and CN 52867 were 22 and 27 Gy, respectively. Plant height and germination percentage decreased with increasing doses of gamma rays. Low dose at 5 Gy could be used to increase tuber yield of these two genotypes of Jerusalem artichoke.
