ABSTRAK Penelitian  ini  bertujuan untuk mengevaluasi karakteristik F1 hasil persilangan blewah (endes) dengan melon (Cucumis melo L.) dari segi kuantitatif maupun kuantitatif. Metode penelitian yang digunakan dalam penelitian ini adalah  metode  eksperimental  dengan  percobaan di lapangan.  Percobaan  dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) dengan 8 perlakuan yaitu 4 tetua dan 4 F1 hasil persilangan  blewah dengan melon. Semua parameter  pengamatan  dianalisa  dengan menggunakan analisis keragaman pada taraf nyata 5%. Jika terdapat perlakuan yang berbeda nyata (P < 0.05) maka dilakuakn uji lanjut dengan uji Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukan terjadi perubahan karakteristik pada keempat F1 hasil persilangan  blewah  dengan  melon,  perubahan karakter  terdapat pada beberapa  sifat  yaitu,  panjang  tanaman,  umur  tanaman  saat  berbunga  betina,  umur  panen, lingkar buah, panjang buah,  bobot buah segar,  berat brangkasan  basah  tanaman  dan berat brangkasan  kering tanaman. Parameter  yang tidak mengalami   perubahan karakteristik  yaitu diameter batang, jumlah bunga jantan dan betina, jumlah cabang produktif dan umur tanaman saat berbunga jantan. ABSTRACT The  objective  of  this  research  was  to  evaluate  the  characteristics  on F1  from  hybridization  between cantaloupe and  melon (Cucumis melo L.) both  quantitative and quantitative traits. The method used in this study is the experimental with experiments in the field. The field design used was  a randomized completely block design with 8 treatments, four parents and the four F1 from crossing between cantaloupe and melon . The  observed  data  were  analyzed  using  analysis  of  variance  at  5%  significant  level  and    the  Duncan Multiple Range Test Test (DMRT) if the effect of treatments was significantly  different. The results showed that there wes a characteristic change of F1  on  the length of plant, the days for flowering of the female flower, days for harvesting,  fruit circumference,  length of fruit , fresh fruit weight , weight of plant fresh matter and weight of plant dry matter. The unchanged characters of  F1 compared to their paents were stem diameter, number of male and female flowers, the number of productive branches and the days for flowering of male flower.

This research is part of an ongoing research project on hybridization between species of yellow-rounded melon and local where F3 generations from the hybridization were evaluated to obtain information on the qualitative and quantitative characteristics of fruits. Seeds of selected F2 fruits with three distinct characters, i.e. 1) netted fruit surface with yellow-orange flesh; 2) ribbed fruits with yellow-orange flesh, and 3) smooth and flat fruit surface with greenish flesh. The results indicated fruits of F2 generation showed varied characteristics. Fruits of F3 generation weighted 0.282 kg to 1.3 kg with sweetness lever ranging from 2 – 4 brix. Qualitative observation indicated that some fruits holding the characteristics of each parent, some with combined characteristics of both parents, and some resulting in a totally new characteristics. Further screening is being conducted to come up with fruits with reasonably good characteristics, either qualitatively or quantitatively.

Once biological control agents of nematodes are introduced into soil, they must function in a very complex and dynamicenvironment. In soil, both nematodes and their antagonists are influenced by other biotic and abiotic factors. However,our knowledge of the effects of these factors in soil is limited. Hence, instead of focusing on the role of individualorganisms in controlling nematode pests, this research aimed to determine the effects of sawdust, microorganisms,and nematodes on trapping activity of Arthrobotrys dactyloides. Experiments were conducted with ?standardslide test? and ?soil microcosm? using soil amended with various concentrations or without sawdust, with thepresence or the absence of microorganisms, and with the presence or the absence of nematodes (Caenorhabditiselegans and/or Meloidogyne javanica). The experiments were carried out with completely randomized design anddata were analyzed with analysis of variance followed by Tukey?s Honestly Significant Different test. Resultsshowed that sawdust did not have direct effect on ring formation and trapping activity of A. dactyloides. However,sawdust did have effect on microorganisms and C. elegans which then these two factors stimulated ring formationand trapping activity of A. dactyloides.
