Abstract
Sweet corn (Zea mays var Saccharata) has high demand but susceptible to downy mildew disease. Downy mildew on maize is a major disease in maize plants and can cause yield losses of up to 100%. The purpose of this study was to obtain and compare information on the character of growth, yield components and downy mildew incidence on various sweet corn lines in the S-4 generation. The study was conducted from August until October 2019 in the Wedomartani Experimental Garden, Faculty of Agriculture, UPN Veteran Yogyakarta. Seven pure line of sweet corn: SB/1-1, SB/1-3, SB/1-4, SB/1-6, SB/2-1, SB/2-2, and 10-2A were planted using a Randomized Block Design with 3 Blocks. Each experimental unit consists of 3 rows and each row consisting of 20 plants. The growth properties: plant height, stem diameter and number of leaves were observed. The yield component: the number of ears, the length of the ear and the diameter of the ear were observed. Disease incidence was observed to determined resistance against downy mildew. Data were analyzed by analysis of variance with 5% significance, followed by Duncan's multiple range test with a level of 5%. SB/2-1 have significantly lowest height and B/1-4 have highest number of leave than other line. There is not significantly different on stem diameter and number of ears. SB/1-3 produce high ear diameter and length. SB/1-1 is having low disease incidence. Keywords: Growth, Crop, Resistance, Sweet Corn, Zea mays var. Saccharata.
