Abstract

Powdery mildew is a fungal disease that causes subtantial losses in melon production around the world including Indonesia. Resistant melon cultivar to powdery mildew is important to increase melon production. Hence, the objectives of this study were to study melon resistance against powdery mildew and its inheritance. A F2 population was obtained from self pollination between F1 ♀ 371795 which derived from ♀ PI 371795 X ♂Action 434 and F1 ♀Action 434 which derived from ♀ Action 434 X ♂ PI 371795. In addition, a test cross population was produce by crossing between F1 with Action 434 as a recessive homozygote pa-rent. Furthermore, powdery mildew resistance in a F1, F2 and test cross populations were tested by inoculating powdery mildew which collected from Ngawi regency. The results were evaluated by Chi-square test (χ2). The results showed that a F1, F2 and test cross populations have different resistance levels to powdery mildew. The resistance to powdery mildew in a F2 ♀ PI 371795 population showed segregation and have 3:1 ratio of Mendel inheritance pattern. On the other hand, resistance to powdery mildew in a test cross with PI 371795 as a parent showed segregation with 1:1 ratio. While resistance in a F2 ♀ Action 434 and test cross populations with Action 434 as a parent did not express Mendel inheritance pattern. Based on the result it could be concluded thatn resistance to powdery mildew in PI 371795 as a female parent is controlled by a single dominant gene (pm-I), while resistance to powdery mildew in action 434 as a female parent is suppose to be controlled by several genes (oligogene).

Abstract

Cucurbits are grown throughout the Java Island as dry season crops. Plants having mosaic, mottling, chlorosis and leaf distortion symptoms were frequently found in most of the cucurbit fields during the survey which conducted in Central Java including Sleman, Kulon Progo, and Klaten during July–September 2000 and 2001. Using double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA); Cucumber mosaic virus (CMV), Cucumber green mottle mosaic virus (CGMMV) and Kyuri green mottle mosaic virus (KGMMV) were found infecting cucurbits. CMV was widespread, infecting 48.9% of the samples tested followed by CGMMV (12.8%) and KGMMV (6.4%), while others samples (31.9%) were not tested, double infections were common with 8.5 % of the samples being infected with two viruses (CGMMV and KGMMV) and 34% with three viruses (CMV, CGMMV, and KGMMV). Severe mosaic and mottle symptoms were associated most often with single infection of CGMMV and KGMMV respectively. In addition, these are the first detections of CGMMV and KGMMV infecting cucurbit plants in Indonesia.

Abstract

This study was conducted to observe and identify viruses from infected shallots in several shallot planting center. The observation was done in eight areas of three provinces (Yogyakarta, Central Java, and East Java). Leaves from shallot plants and shallot germination showing virus symptoms were examined. The leaves were then investigated to identify viruses infecting shallots using Enzyme-Linked Immunosorbent Assay (ELISA). The result revealed that the type of virus symptoms infecting the shallots was a mozaic symptom with yellow strips. The ELISA analysis showed that Tawangmangu Biru shallot cultivar plants sampled from Blumbang, Tawangmangu (Central Java) and Philiphine Bima shallot cultivar seeds collected from Srigading, Sanden, Bantul (Yogyakarta) were positively infected by Onion Yellow Dwarf Virus (OYDV). The result also revealed that Biru, Kuning Tablet, Lokal Tawangmangu, and Bima Curut shallot cultivars had the potency to be virus resistant plants and could be considered as candidates for breeding program.

Abstract

Papaya ringspot virus (PRSV) is one of potyviruses causing severe damage to the production of cucurbit crops including melon, however resistant melons to PRSV have not yet commercially available. To find resistant genetic source of melons against PRSV, sixty three melons were manually inoculated with PRSV-papaya strain (PRSV-P) isolated in Thailand. Levels of resistance to PRSV-P accumulation in melon leaf tissue were evaluated using a combination of visual symptom observation and RT-PCR analysis. Among melons tested, Yamatouri, Mawatauri, PI 414723, and PI 371795 showed to be resistance to PRSV-P To study the inheritance of resistance to PRSV-P, breeding experiments were conducted by crossing the resistant Yamatouri with susceptible Vakharman. The genetic analysis results revealed that a single dominant gene conferred resistance to PRSV-P in Yamatouri and its generation.

Abstract

This research aims to develop cultivars with superior phenotypes of melon and high level of productivity. This research used the individual results of crossing between melon  ♀ ‘Hikapel' with ♂ 'Hikadi Aromatik'. The research included qualitative and quantitative phenotype characterization test. The research was conducted in Center of Agrotechnology Innovation University of Gadjah Mada (PIAT-UGM), Kalitirto, Berbah, Sleman, Yogyakarta and Laboratory of Genetics Faculty of Biology UGM on December 2016 until March 2017. Quantitative data analysis used ANOVA testing through PKBT-STAT 2.02 software with Random Complete Block Design (RCBD) method at significance level of 1% and 5%. Melon 'Hikapel Aromatik' has several advantages including oval shape, without net, without lobes, crispy texture, skin-collored yellow RHS (6A), has a 7-14 brix, has volatile aromatic compound and transposon influenced. Based on the results of recapitulation of variance, the characters of 'Hikapel Aromatik' was not uniform.

Abstract

Coastal area around sand dune on the Bocor Beach potentially used as agricultural land especially melon cultivation. It was located at Buluspesantren Subdistric , Kebumen Distric, Central Java. Cultivation techniques in that land were not green cultivation .The use of pesticides, non-organic material, and plant cutting in the area of sand dune have a potential to damage the environment. This event was aimed to introduce the technique of green melon cultivation so that melon cultivation around sand dune can develop and sustainable. The technique of melon cultivation used in this activity was production of melon superior seed and fruit selection. Melodi Gama3 (MG3) was one of the superior seed which used in this activity. Superior seed was able to reduce the use of pesticides and fruit selection can produce fruit in a high quality. Then the group of farmers trained to use local potential as a substitute for a common material used by other farmers. Palm midrib instead of bamboo, pandanus fiber as a rope replacement, and some other potential materials can be used. Cultivation techniques are transfered to farmers group by training and farmers models. The results of economic analysis indicates that the green melon cultivation techniques are able to increase the income of farmers in the area melon around sand dune. After this event, the farmers was expected to develop environmentally welfare farming techniques in the area around sand dune in Bocor Beach.
