Abstract

Fusarium wilt is a serious disease attacking chili plants in Central Java which cause lost of chili productivity. Fusarium wilt is caused by pathogenic fungi Fusarium oxysporum, which is host specific. The objectives of this research were to characterize the pathogenic F. oxysporum as the causal agent of fusarium wilt in chili plants and to observe the virulence of the pathogen. Fungal pathogen was isolated from Tawangmangu as an endemic area of fusarium wilt in Central Java. The fungi was characterized morphologically and identified molecularly by its internal transcribed spacer regions (ITS regions). Pathogenicity test was done to observe the virulence of the pathogen. One pathogenic strain was isolated from Tawangmangu, Karanganyar and was identified  morphologically and molecularly as F. oxysporum.

Abstract

The aim of this research is to study the phenotypic character and growth of layered chickens. In this study, crosses between G4 Layer chickens were carried out which resulted in G5 Layer chickens. Morphological characters, growth weights and measuring the feed-conversion ratio (FCR) were observed. The results obtained were 10 individuals of G5 Layer chickens with the proportion of male gametes (70%) and female gametes (30%). Phenotypic characters are brown fur color and a combination of brown and white. The value of Feed Conversation Ratio (FCR) is 1.67 and the average weight growth of G5 Layer chickens reaches 491.2 grams at the age of 7 weeks.
