<p>Cucurbits are the group of vegetables belongs to the family Cucurbitaceae. Oriental pickling melon (<em>Cucumis melo </em>var. <em>conomon)</em> is one among the melon group vegetables belongs to <em>Cucurbitaceae</em> family<em> </em>with a chromosomal number 2n=24. It is also called as golden melon or culinary melon in English. In Karnataka it is called by local names as <em>Sambar Southe, Mogghe kayi or Mangalore southe</em>. A field experiment was carried out at University of Horticultural Sciences Bagalkot, Karnataka to study the reaction of oriental pickling melon to fruit fly pest, diseases like powdery mildew and downy mildew disease. The results revealed that least infestation of fruit fly was recorded in Sirsi Local (40.00 %) followed by BCMCO-01 (41.30 %), BCMCO-02 and BCMSO-03 (41.75 % each). Highest infestation of fruit fly was recorded in Sirsi-2-13 (65.07 %) followed by BCMSO-04 (59.90 %). Among the genotypes, none of them had showed resistant to infestation and found susceptible to fruit fly attack in unsprayed condition. Least infestation of powdery mildew was found in Mysore Local (37.71 %) followed by Sirsi Local (37.99 %) and BCMSO-03 (39.76 %). Whereas highest mildew in GR-3 (46.08 %) followed by Sirsi-1-13 (45.81 %) and BCMCO-02 (45.75 %). Least infestation of downy mildew was observed in BCMCO-02 (14.00 %) followed by Sirsi Local (16.29 %) and BCMSO-03 (17.43%). Highest infestation was found in GR-2-1 (27.07%) followed by GR-4 (26.58 %) and GR-4-1 (26.23 %). Most of the genotypes were moderately susceptible to downy mildew disease.</p>

Downy Mildew Disease

Culinary melon also known as non dessert cucumber (Cucumis melo subsp. agrestis var. acidulus) belongs to the family Cucurbitaceae. It is widely cultivated in Southern parts of Indian subcontinent. It is mainly utilized for preparation of lentil soup, sambar, dosa, palya and chutney. 70 accessions were collected from six South Indian states namely Karnataka, Kerala, Andhra Pradesh, Tamil Nadu, Telangana and Goa. The accessions were evaluated for incidence of downy mildew resistance during Kharif 2018 under natural condition. The percent disease index (PDI) for downy mildew ranged from 3.70 to 48.64%. 10 accessions showed resistance to downy mildew. Among them, accession MS21 showed resistance with average least PDI of 3.70 followed by MS 6 (6.54). 50 accessions were found to be moderately resistant with average PDI ranging from 20 to 39.80. 12 accessions were found susceptible with PDI ranging from 41 to 49. None of the accession was found highly susceptible to the disease. The resistant accessions can be utilized as donor parents for resistant breeding in the improvement of culinary melon as well as melon group of vegetables.

Background: A powdery mildew-resistant cultivar of melon is needed to increase melon yield crops. Meloni is a superior melon cultivar bred through a crossing between ♀ SL-3 and ♂ PI 371795, resulted by the Laboratory of Genetics and Breeding, Faculty of Biology, UGM. This study aimed to determine the level resistance of Meloni to powdery mildew infection and to identify the powdery mildew species that infected Meloni based on morphological characters. Methods: Meloni seeds were germinated and planted in the greenhouse of PIAT UGM. Powdery mildew spores were inoculated into the leaves after ±2 weeks of age. Leaf infected were scored using the gridline every 3 days for 6 weeks. Scoring results were converted to the diseases index score. Furthermore, powdery mildew species was identified using morphological characters. Results: Meloni had a tolerance level of resistance to the powdery mildew infection. Based on the morphological characters with fibrosin bodies, conidia ovoid-shape and the position of the germ tube in the lateral part of the conidia, powdery mildew that infected Meloni was expected as P. xanthii. Conclusions: Meloni can be expected as an alternative to superior melon seeds resistant to pest and disease infections especially powdery mildew.

Field evaluations for resistance against downy mildew, incited by Pseudoperonospora cubensis (Berk. & M.A. Curtis) Rostovzev were conducted on 1076 U.S. Plant Introductions (PI) of Cucumis melo L. (melon). A disease index (DI) was calculated for each entry that had one or more resistant plants. Based on DI, PIs 271329 and 401644 were the most resistant overall (DI = 2.6 and 2.8, respectively). However, resistant plants exhibiting reaction type (RT) 3 were identified in 68 accessions, and 110 accessions had moderately resistant (RT 2) plants.

Abstract. Pratama OA, Tunjung WAS, Sutikno, Daryono BS. 2019. Bioactive compound profile of melon leaf extract (Cucumis melo L. ‘Hikapel’) infected by downy mildew. Biodiversitas 20: 3448-3453. Plants express specific secondary metabolites (phytoalexin) in response to infection. Downy Mildew which infects melon plants (Cucumis melo L. ‘Hikapel’) caused by Pseudoperonospora cubensis Rostovtsev. Hikapel is one of superior melon cultivar produced from research in the Laboratory of Genetics, Faculty of Biology, Universitas Gadjah Mada, Yogyakarta, Indonesia. Bioactive content of Hikapel melon leaf under normal condition and infected by Downy Mildew yet to be researched. This research aims to screen bioactive profile of Hikapel leaf extract that has potential as phytomedicine. Leaf extract is compared between healthy plants and infected by Downy Mildew. Dried melon leaf was powdered using mortar and pestle. Leaf powder was extracted using hexane solvent. Extract was analyzed using a Shimadzu GCMS-QP2010S. Analysis found useful compounds like phytol, methyl ricinoleate, methyl linoleate, methyl stearate, and 1-hexacosanol. with therapeutic activity such as antibacterial, antifungal, antioxidant, antiinflammatory, antidiuretic, antidiarrheal, lowering blood LDL-C level, insulin level booster, antiproliferative, and anticancer. Some bioactive compounds are only synthesized in Hikapel melon leaf under stress conditions.

A field experiment was conducted to evaluate the efficacy of ametoctradin 300 g/l + Dimethomorph 225 g/l sc against downy mildew disease of grapes for 2 seasons at Agricultural Research Station Bagalkot district. It was found that Ametoctradin 300 g/ l + Dimethomorph 225 g/l sc is highly effective in reducing the downy mildew disease in grapes. Further the phytotoxicity was not observed in the chemical Ametoctradin 300 g/l + Dimethomorph 225 g/l sc to the treated plots of grapevine even at high doses and also exhibiting an appreciable increase in grape berry yield.
