Abstract

Anthracnose disease in shallots caused by the pathogenic fungus Colletotrichum gloeosporioides is one of the main diseases that can thwart the planting and yield of shallots up to 100 percent. The purpose of this study was to obtain shallot clones that have high resistance to anthracnose disease and produce high yields of true seeds of shallot. The screening of shallot clones has been carried out at the Agricultural Technology Testing and Development Installation - Indonesia Vegetable Research Institute at an altitude of 1250 m above sea level. Testing time was carried out in September-November 2017. Tests for resistance to anthracnose were carried out by natural inoculation in the field and artificial inoculation at the Screen House. Tests to obtain shallot seeds were carried out in the field under a plastic shade. The experimental design used was a randomized block design with 10 clones/varieties of treatment and four replications. The clones tested were A, D, E, F, K and the varieties Trisula, Bali Karet, Maja Cipanas, Bima Brebes and Sumenep as parents and comparisons. The selection results showed that clone A had resistance to anthracnose (C gloeosporioides) with the criteria of moderate resistance with the production of 24.42 tons/ha of wet tubers and 12.84 tons of dry tubers/ha and yield of 2.16 grams of seeds per 1000 seeds.
