Selection Response for Increased Grain Yield in Two High Oil Maize Synthetics

Selection for increased oil level in maize showed the increase was associated with decrease in starch concentration, kernel weight, and grain yield. The study was conducted with the objectives: (1) to evaluate response to six cycles for increased grain yield in the high oil maize Alexho Elite (AE: 60-90 g kg-1 oil concentration) and Ultra High Oil (UHO: 100-140 g kg-1 oil concentration) using inbred tester B73; (2) to measure responses to selection for increased grain yield with changes in yield components; and (3) to determine a suitable tester. Previously the two synthetics had been selected for oil concentration. After six cycles, the six genotypes i.e. AE C0, AE C3, AE C6, UHO C0, UHO C3, and UHO C6 were testcrossed to B73, LH185, and LH202 inbreds (40 g kg-1 oil concentration) to a total of 18 testcrosses. Two field experiments were used to evaluate selection in AE and UHO testcrosses. The study showed selection using inbred tester B73 in AE and UHO was effective in increasing grain yield of AE testcrosses without changing (i.e. decreasing) oil and protein concentrations. AE testcrosses produced higher grain yield and greater selection response for grain yield than UHO testcrosses. LH185 was best for grain yield in AE and UHO testcrosses. Increase in grain yield in most of the testcrosses was associated with increases in starch concentration, kernel weight, kernel number, and grain weight

Validitas Gejala Klinis sebagai Indikator untuk Memprediksi Kasus Malaria di Indonesia (Analisis Data Riskesdas 2010)

Salah satu upaya yang cukup efektif dalam surveilans malaria adalah melakukan screening (penapisan) malaria untuk meningkatkan sistem kewaspadaan dini di kelompok masyarakat daerah endemis malaria. Hasil penapisan positif atau meragukan harus dirujuk ke dokter untuk penegakkan diagnosis dan pengobatan. Penelitian ini bertujuan untuk menganalisis validitas gejala klinis sebagai indicator untuk memprediksi kasus malaria di Indonesia dengan menggunakan disain cross-sectional. Sampel dalam penelitian ini adalah semua responden yang diwawancarai, dilakukan pemeriksaan darah dengan Rapid Diagnostic Test (RDT). Validitas gejala klinis diukur dengan melakukan summary statistic untuk diagnostic test. Di wilayah endemis tinggi sensitivitas gejala klinis demam saja sebagai prediktor malaria hanya 26,9% (95% CI: 22-32,2) dan PPV 11,4% (95% CI: 9,2-13,9) dengan spesifisitas 96% (95% CI: 95,6-96,3). Sensitivitas, PPV, dan spesifisitas gejala demam saja di daerah endemis sedang secara berturut-turut adalah sebesar 26,1% (95% CI: 17,5-36,3), 5.0% (95% CI: 3,2-7,4), dan 96,9% (95% CI: 96,6-97,2). Di daerah endemis rendah sensitivitas demam sebagai alat diagnosa kasus malaria hanya sebesar 3,5% (95% CIH: 1,6-6,6) dengan PPV 1,1% (95% CI: 0,5-2,1) sedangkan spesifisitas 98% (95% CI: 97,8-98,1). Kombinasi gejala klinis demam, menggigil, sakit kepala, berkeringat, mual, dan muntah dalam analisis data Riskesdas menunjukkan sensitifitas yang lebih tinggi bila dibandingkan dengan demam saja (36,4%). Sebaliknya PPV kombinasi gejala tersebut lebih rendah bila dibandingkan dengan PPV demam saja (3,8%). Gejala klinis malaria kurang valid untuk digunakan untuk mendeteksi kasus malaria baik pada daerah endemis tinggi, sedang, maupun rendah. Akan tetapi penggunaannya untuk daerah endemis tinggi masih dimungkinkan, seperti yang direkomendasikan oleh WHO terutama untuk anak-anak.Kata kunci: malaria, gejala klinis, validitas, sensitivitas, spesifisitasAbstractOne of the effective ways in malaria surveillance is screening to improve early warning system in communities in malaria endemic area. Positive screening or doubted results should be referred to physician for diagnosis and treatment. The aim of this study was to analyse the validity of clinical symptoms as an indicator to predict malaria case in Indonesia. Samples of this study were all respondents interviewed by the National Health Research in 2010 whose blood were examined for malaria using RDT. Validity of clinical symptoms was analysed by using summary statistic for diagnostic test. The results showed that the sensitivity of fever alone as a predictor of malaria in high endemic area was only 26.9% (95% CI: 22-32.2). However, the specificity was 96% (95% CI: 95.6-96.3) and positive predictive value (PPV) 11.4% (95% CI: 9.2-13.9). In low endemic area, sensitivity and PPV of fever alone were low with 3.5% (95% CI: 1.6-6.6) and 1.1% (95% CI:0.5-2.1) respectively. On the other hand, the specificity was relatively high with 98% (95% CI: 97.8-98.1). Combination of fever, chill, headache, sweat, nausea, and vomit showed higher sensitivity (36.4%; 95% CI:28.9-40.5) and specificity (84.2%; 95% CI: 83.6-84.8) compare to fever alone in high endemic area, whereas the PPV was lower (3.8%: 95% CI: 3.1-4.6). In low endemic area, symptoms combination had a higher sensitivity (14.7%; 95% CI: 10.6-19.7) compare to fever alone. However, the specificity and PPV were lower with 91.2% (95% CI: 90.9-91.4) and 1% (95% CI: 0.7-1.4) respectively. Conclusion: The validity of clinical signs and symptoms to diagnose malaria is low in high and low transmission area. However, the use of clinical symptoms as a predictor of malaria is still possible in high transmission area as recommended by WHO, particularly for children.Key words: malaria, clinical symptoms, validity, sensitivity, specificit

Perbaikan Genetik Gandum Tropis Toleran Suhu Tinggi dan Permasalahan Pengembangannya pada Daerah Dataran Rendah

Perbaikan genetik gandum melalui program pemuliaan di Indonesia diawali dengan mengintroduksi galur-galur elit dari berbagai negara yang dinilai cocok dengan agroekosistem tropis Indonesia karena Indonesia tidak memiliki plasma nutfah lokal. Keragaman genetik yang luas sangat dibutuhkan untuk mendapatkan varietas gandum tropis. Program peningkatan keragaman genetik gandum yang sudah berjalan ialah pemuliaan melalui persilangan dan mutasi (biji dan variasi somaklonal). Jenis gandum yang dapat ditanam di lingkungan tropis Indonesia ialah Triticum aestivum pada ketinggian > 1.000 m dpl. Pengembangan gandum tropis < 1.000 m dpl perlu didukung pemuliaan mulai dari pembentukan populasi sampai pelepasan varietas dengan metode shuttle breeding. Evaluasi galur-galur introduksi pada dataran rendah memperoleh beberapa galur dan varietas toleran (Oasis, Selayar) dan peka (Dewata, HP1744). Pada galur dan varietas tersebut selanjutnya dilakukan persilangan (single cross dan convergent breeding) dan mutasi dengan iradiasi sinar gama diikuti shuttle breeding. Single cross melalui shuttle breeding menghasilkan 30 galur adaptif < 1.000 m dpl, sementara dari convergent breeding diperoleh populasi F4. Pemuliaan melalui iradiasi sinar gama pada biji memperoleh 15 galur mutan M7, sementara melalui variasi somaklonal kultur jaringan menghasilkan populasi mutan M4. Hampir semua karakter agronomi yang dipelajari toleransinya terhadap cekaman suhu tinggi dikendalikan secara poligenik dengan aksi gen aditif dengan pengaruh epistasis duplikat maupun komplementer
