ABSTRAK<br />Kajian model stabilitas hasil dilakukan untuk uji multi lokasi musim<br />pada galur tembakau Virginia rajangan Bojonegoro di tigs lokasi,<br />Kedungadem, Pekuwon dan Sugihwaras, Jawa Timur pada empat musim<br />tanam 1997, 1998, 1999, dan 2001. Tiga lokasi yang dipilih merupakan<br />daerah pengembangan tembakau Virginia Bojonegoro, masing - masing<br />berjarak antara 15 - 20 km satu sama lain. Empat belas galur yang diuji<br />merupakan hasil seleksi sejak tahun 1990. Rancangan percobaan yang<br />digunakan di setiap lokasi adalah rancangan kelompok dengan tiga<br />ulangan. Ukuran petak percobaan 8,6 m x 6,75 m, jarak tanam 90 x 45<br />cm, dengan satu tanaman per lubang. Penentuan stabilitas hasil dengan<br />menggunakan model kualitatif YAU dan HAMBLIN (1994) dan model<br />kuantitatif menurut PERKINS dan JINKS (1968). Hasil analisis<br />menunjukkan dengan model kualitatif galur nomor 13, 7, 10, 6, dan 5<br />merupakan galur yang stabil dengan hasil rajangan kering di atas hasil rata-<br />ratanya, sedang dengan model kuantitatif galur nomor 9,11,14, 6, dan 10<br />merupakan galur yang stabil dengan hasil ranjangan kering di atas rata-<br />ratanya. Pengukuran stabilitas hasil dengan model kuantitatif lebih<br />informatif dibandingkan dengan model kualitatif.<br />Kata kunci : Tembakau, Nicotiana tabacum, tembakau Virginia, uji<br />multilokasi, stabilitas hasil, Jawa Timur<br /><br />ABSTRACT<br />Study of qualitative and quantitative yield stability model<br />for season muUilocation test of Bojonegoro sliced Virginia<br />tobacco<br />Study of quantitative and qualitative stability model for multi-<br />location-season test of Bojonegoro sliced Virginia tobacco conducted in<br />three locations: Kedungadem, Pekuwon and Sugihwaras, East Java in<br />1997; 1998; 1999, and 2001. The selected locations were the area of the<br />Virginia tobacco development. The locations were 15-20 km apart from<br />one another. Fourteen lines of sliced Virginia tibacco tested were the result<br />of selection since 1990, tested in three locations and four growing seasons.<br />The experiment used a randomized blok design with three replications in<br />each location. Plot size was 8,6 m x 6,75 m, plant distance was 90 cm x<br />45 cm, one plant per hole. The stability parameters were measured by<br />qualitative model according to YAU and HAMBLIN (1994) and<br />quantitative ones were measured according to PERKINS and JINKS<br />(1968). The result of the analysis using qualitative model showed that lines<br />No 13, 10, 6, dan 5 were stable genotypes with the yield above its average<br />while based on quantitative model and lines No 9,11,14, 6, dan 10 were<br />stable genotypes with the yield above its average. Measurement of yield<br />stability using quantitative model was more informative compared to<br />qualitative model.<br />Key words: Tobacco, Nicotiana tabacum, virgina tobacco, multi-location<br />test, yield stability.
