Abstract

Mosaic disease outbreaks on chili (Capsicum annum) associated with Cucumber Mosaic Virus (CMV) is serious worldwide. The use of resistant cultivars is an effective control to reduce the loss of yield caused by virus’s infections. The objective of this study is to detect the resistant characters of CMV in chili using OPH-17 and OPA-20 RAPD primers. The inoculation of CMV in PSPT-C11, C17-PSPT, ICPN 7 # 3 and 1 Chilibangi 1 varieties cause systemic mosaic symptoms vary from mild mosaic to the mosaics with malformations. PSPT-C11 varietiy showed rather resistant, while the varieties PSPT-C17 and Chilibangi 1 are susceptible, and ICPN 7 # 3 is very susceptible. OPH-17 and OPA-20 primers could not be used to determine the resistance differences against CMV in PSPT-C11, C17-PSPT, ICPN 7 # 3 and Chilibangi 1 varieties.

Abstract

The experiment aimed to find out the effect of different manure materials and proper corn plant spacing on weedgrowth and sweet corn yield. The experiment was conducted in Agricultural Training, Research and Development(ATRD), Gadjah Mada University. The experiment was a factorial experiment in a split plot design with threereplications. As the main treatment was different manuring, consisting of (1) no manure, (2) cow manure, (3) goatmanure, and (4) chicken manure. Plant spacing consisting of : (1) 100 cm x 20 cm, (2) 50 cm x 40 cm, and (3) 80cm x 25 cm, served as sub treatments. The results showed a significant interaction between manuring and plantspacing with respect to weed growth and sweet corn yield. The lowest weed dry weight when corn plants werespaced at 50 cm x 40 cm, and chicken manuring was given. Chicken manuring produced the highest ear yield,162.43 g/plant; mean while, plant spacing of 50 cm x 40 cm produced the highest ear yield, amounting to 154.44g/plant. Chicken manuring to sweet corn plants spaced at 50 cm x 40 cm gave the largest marketable ears, 11.567t/ha.
