"This research was aimed to initially test 40 rainfed lowland dedicated GSR lines along with 3 checks, i.e.
PSBRC68, Situbagendit, and Silugonggo. The trial was conducted in ICRR experimental station in Sukamandi
with irrigation only until 2 weeks after transplanting and during flowering. The trial was conducted during DS
2012 following Randomized Complete Block Design of three replication in 1 m x 1 m plot size and planting space
of 20 cm x 20 cm. Transplanting was conducted to 21 days old seedings. The results showed that identified five
line that have higher yields than the best check Silugonggo ( 4.22 t/ha ), which Luyin 46 ( 5.18 t/ha ), 926 ( 5.12
t/ha ), SACG - 7 ( 4.46 t/ha ), LH1 ( 4.36 t/ha ) and Weed Tolerant Rice ( 4.30 t/ha ). A total of three lines , namely
ZX788 ( 84 HSS ), 08FAN4 ( 89 HSS ) and D100 ( 91 HSS ) has a ripe age is significantly more early maturity of
the check is very early maturing Silugonggo ( 95 HSS ). GSR lines tested had similar agronomic characters with
existing varieties, among others, from 46.67 to 100.2 cm plant height, number of productive tiller 6-10 fruit,
flowering age 56-86 HSS, or physiological maturity round 84 -102 HSS, filled grain 47-185 grains per panicle,
1000 grain weight 17.94 to 32.34 g, and the results ranged from 0.95 to 5.18 t/ha.
Penelitian ini bertujuan untuk menguji awal daya adaptasi 40 galur GSR untuk padi sawah tadah hujan

"Identification of Polymorphic Markers for Breeding of Rice Tolerant to Phosphorus Defficiency. Joko Praseti- yono, Hajrial Aswidinnoor, Sugiono Moeljopawiro, Didy Sopandie, and Masdiar Bustamam. Information on poly- morphisms among rice parents are very important in rice breeding for tolerance to phosphorus defficiency. A study was conducted at the Molecular Biology Laboratory, Indonesian Center Agricultural Biotechnology and Genetic Resources (ICABIOGRAD) from October 2006 to July 2007 to identify polymorphism markers from 6 rice genotypes. The rice genotypes, i.e., Dodokan, Situ Bagendit, Batur, Kasalath, NIL-C443, dan K36-5-1-1 were analyzed for polymorphisms using 496 SSR markers, which cover the rice genomes. Seven of the 496 markers were used as foreground and recombinant selection markers, and the rests (489 markers) were used as background selection markers. PCR amplifi- cations were separated on a 5% polyacrylamide gel and colored by the silver staining method. Three different mar- kers among the seven foreground and recombinant selec- tion markers were selected from each crossing, which are tightly linked with Pup1 gene and have a distance less than 5 cM. These markers are Dodokan vs Kasalath (RM277, SSR3, RM519), Dodokan vs NIL-C443 (RM277, SSR3, RM519), Dodokan vs K36-5-1-1 (RM277, SSR3, RM519), Situ Bagendit vs Kasalath (RM28102, SSR3, RM519), Situ Bagendit vs NIL- C443 (RM28102, SSR3, RM519), Situ Bagendit vs K36-5-1-1 (RM511, SSR3, RM519), Batur vs Kasalath (RM277, RM1261, RM519), Batur vs NIL-C443 (RM277, RM1261, RM519), and Batur vs K36-5-1-1 (RM28102, SSR3). Variations in back- ground selection primers were found in each chromosome and in each parent combinations. Primers on chromosome 4, 5, and 12 showed the lowest polymorphisms; more primers are needed for these chromosomes."

"ABSTRAK
Pengendalian merupakan kegiatan penting dalam rangka mengatasi masalah kehilangan hasil akibat serangan organisme pengganggu tanaman khususnya tanaman padi sawah. Di antara cara-cara pengendalian yang ada., pengendalian dengan menggunakan bahan kimia (pestisida) yang paling banyak dipakai oleh petani.
Pengendalian organisme pengganggu tanaman dengan berbagai permasalahannya memberikan tantangan yang perlu segera diatasi dalam rangka mengamankan produksi dari gangguan organisme pengganggu.
Perubahan lingkungan hidup buatan karena pestisida terlarang yang dialami petani padi sawah, mengakibatkan kualitas lingkungan hidup menurun. Oleh karena itu menuntut mereka untuk dapat mengembangkan cara-cara pengendalian yang ada dengan jalan melakukan perpaduan antara cara pengendalian yang satu dengan cara pengendalian yang lain atau yang dikenal dengan sebutan PHT (Pengendalian Hama Terpadu). Dari kenyataan di lapangan ternyata terdapat indikasi tentang rendahnya kemampuan petani dalam mengatasi masalah gangguan organisme pengganggu tanaman. Hal ini diduga ada hubungan antara tingkat pendidikan, pengetahuan dan pengalaman dengan penggarapan sawah, cara memilih pestisida terlarang , cara bertindak terhadap pestisida terlarang, kesadaran terhadap bahaya pestisida terlarang, lingkungan dan perizinan pestisida yang berlaku.
Penelitian ini dilakukan di daerah Kabupaten Bekasi, Propinsi Jawa Barat dengan sampel sebanyak 300 petani padi sawah yang berlokasi di dua kecamatan, yaitu Kecamatan Sukatani dan Kecamatan Tambelang. Sampel ini diambil dengan cara purposive sampling untuk menentukan lokasi penelitian, dan randomize sampling bagi petani penggarap sawah sebagai responden. Secara umum penelitian ini bertujuan untuk mencegah penggunaan pestisida terlarang oleh petani pada lingkungan padi sawah di Kabupaten Bekasi.
Untuk memperoleh data yang diperlukan, menggunakan daftar pertanyaan dan wawancara secara mendalam. Data yang sifatnya kuantitatif dianalisis dengan uji statistik Chi Kuadrat dan Koefisien Kontingensi. Data yang kualitatif dianalisis dengan cara interpretasi dan pemahaman.
Dari analisis data diperoleh bahwa :
1. Serangan serangga hama yang terluas dan dominan menyerang tanaman padi adalah penggerek batang pada varietas IR64 dan Cisadane, di lapangan dikendalikan dengan insektisida karbamat dengan dosis 1-3 1/kg/musim tanam;
2. Umumnya petani padi sawah berstatus penduduk tetap dengan umur terbanyak ditemukan yaitu 35 - 43 tahun dan sudah bermukim di atas 10 tahun dan terbanyak melakukan penggarapan sawah di atas 1 - 3 ha pada sawah milik orang lain;
3. Pekerjaan tetap petani selain bertani ada yang berdagang, buruh harian, pegawai desa dan mengganggur dengan memiliki anggota keluarga terbanyak 4 - 5 jiwa serta berpenghasilan di atas 1 - 2 juta rupiah per tahun dan pengeluaran di atas 100 - 200 ribu rupiah per bulan;
4. Cara petani memilih pestisida terlarang dipengaruhi Oleh pendidikan non formal, pengetahuan dan pengalaman (C.C ' a 0,05), tetapi tidak dipengaruhi oleh pendidikan formal (C.C < a 0,05);
5. Cara petani bertindak terhadap pestisida terlarang dipengaruhi oleh pengetahuan (C.C > a 0,05), tetapi tidak dipengaruhi oleh pendidikan formal, pendidikan non formal dan pengalaman (C.C < a 0,05);
6. Kesadaran petani terhadap bahaya pestisida terlarang dipengaruhi oleh pendidikan non formal, pengetahuan dan pengalaman (C.C > a 0,05), tetapi tidak dipengaruhi oleh pendidikan formal (C.C C a 0,05);
7. Kesadaran petani terhadap lingkungan dipengaruhi oleh pendidikan formal, pendidikan non formal dan pengetahuan (C.C > a 0,05), tetapi tidak dipengaruhi oleh pengalaman (C.C 4 a 0,05);
8. Kesadaran petani terhadap perizinan pestisida dipengaruhi oleh pendidikan formal, pendidikan non formal dan pengetahuan (C.C > a 0,05), tetapi tidak dipengaruhi oleh pengalaman (C.C < a 0,05);
9. Penggarapan sawah dipengaruhi oleh pendidikan non formal dan pengetahuan (C.C > a 0,05), tetapi tidak dipengaruhi oleh pendidkan formal dan pengalaman (C.C < a 0,05).

Control of crop pests has been an important activity in overcoming yield loss problems due to their attack particularly on rice. Among available control method, chemical control is mostly and widely used by farmers. Subsequently, control of crop pests along with the emerging problems give us challenge which should be undertaken, so that crop production can be exempted from pest attack.
Changes in artificial environment due to the use of banned pesticides experienced by farmers have resulted. in the reduction of the environment quality. Therefore, the farmers are demanded to be capable of developing existing control measures and combining them in a compatible manner as well, which is then so called Integrated Pest Management (IPM). However, in fact, there has been an indication on the capability of the farmers in solving this problem. In this case maybe there are relation between levels of knowledge, education, experience with paddy field cultivated, ways of selecting banned pesticides, handling banned pesticides, awareness of banned pesticide danger, their environment, and pesticide permission .
This study was carried out in Kabupaten Bekasi, West Java Province with the sample comparising of 300 rice field farmers. Two kecamatan in this area were chosen, viz. Kecamatan Sukatani and Kecamatan Tambelang. These sample were taken by using purposive method to decide locations of study, and using randomized sampling to select the rice field farmers as the respondents. In general, this study was aimed to figure out the effects of chemical control using banned pesticides to humans and the environment in Kabupaten Bekasi.
To obtain required data, a list of questions and thorough interview were used. Quantitative data were statistically analyzed by using Chi-square test and Coefficient of Contingency (C.C), whereas qualitative data were analyzed with interpretation and comprehension methods.
Data analysis shows that :
1. The stem borer is the predominantly attacking insect pest to rice of IR-64 and Cisadane varieties and is widely present in the rice field. The chemical control is mostly by using carbamate insecticide with the dosage of I - 3 1/kg/planting season;
2. The status of rice farmers is generally residents with the age ranging from 35 to 43 years old and have already resided for more than 10 years. Among these are mostly doing farming on 1 - 3 ha of rice field belonging to others;
3. Instead of farming, farmers also sell things, become daily laborers, village officers, and some others are unemployment. The member of family is mostly 4 - 5 with the income of more than two million rupiah/year and the outcome of more than two hundreds thousand rupiah/month
4. The farmers' way of selecting banned pesticides is influenced with non formal education, knowledge and experience (C.C > a 0.05), but is no influenced with formal education (C.C < a 0.05);
5. The farmers' way of handling banned pesticides is influenced with knowledge (C.C > a 0.05), but is not influenced with formal education, non formal education and experience (C.C < a 0.05);
6. The farmers' awareness to the danger of banned pesticide is influenced with non formal education, knowledge and experience (C.C > a 0.05), but is not influenced with formal education (C.C ? a 0.05);
7. The farmers' awareness to the environment is influenced with formal education, non formal education and knowledge (C.C > a 0.05), but is not influenced with experience (C.C < a 0.05);
8. The farmers' awareness to pesticide approval is influenced with formal education, non formal education and knowledge (C.C > a 0.05), but is not influenced with experience (C.C < a 0.05);
9. Rice cultivation is influenced with non formal education and knowledge (C.C > a 0.05), but is not influenced with formal education and experience (C.C < a 0.05).
