Hubungan sifat-sifat agronomis terhadap indeks tanaman dan kadar nikotin telah dicari dengan analisis lintas. Tujuan dari analisis adalah untuk mengetahui pcubah bebas yang sangat mempengaruhi peubah yang tidak bebas, indeks mutu dan kadar nikotin daun, sehingga dapat mengurangi banyaknya pengamatan yang dilakukan. Data pengamatan agronomis yang meliputi : jumlah daun/pohon, luas daun ke-7, luas daun ke-15, bobot rajangan kering/ha, indeks mutu dan indeks tanaman diperoleh dari percobaan pemupukan tiga galur harapan tembakau Virginia di kebun percobaan Pekuwon Bojonegoro dari bulan Mei sampai dengan Oktober 2002. Hasil analisis lintas antara indeks tanaman dengan peubah bebas di atas menunjukkan bahwa indeks tanaman sangat ditentukan oleh bobot rajangan kering dengan koefisien lintas pm-1.03367 dan koefisien dcterminasi parsial 102%. Hubungan lintas bcrantai melalui pcubah rajangan kering dan indeks mutu menunjukkan bahwa luas daun kc-7 sangat mempengaruhi rajangan kering dengan koefisien lintas (p„i)- 0.85257 dan rajangan kering sangat mempengaruhi indeks tanaman dengan koefisien lintas (p,x,)= 0.95639, indeks mutu pengaruhnya terhadap indeks lanaman sangat kecil dengan koefisien lintas p,M = 0.12316. Analisis lintas antara kadar nikotin daun dengan ke lima peubah tidak baik (unfit) dengan koefisien sisa p„,= 0.6827 melebihi koefisien lintas yang lainnya. Dengan pentingnya peubah rajangan kering ini maka penjualan daun segar yang dilakukan oleh petani tidak dianjurkan.Kata kunci: Nicotiana tabacum, tembakau Virginia, analisis lintas, jumlah daun, luas daun, indeks tanaman, indeks mutu, kadar nikotin, bobot rajangan ABSTRACT Path analysis of agronomical characteristics on crops index and nicotine content of Virginia tobacco Bojonegoro The relationship between agronomical characteristics and crops index or leaf nicotine content has been studied by using path analysis. The purpose of this analysis was to determine the independent variables which most affected the dependent ones as crops index and leaf nicotine contain, so that it could reduce the number of independent variables. The agronomical characteristics consist of leaf number/plant, seventh and fiteenth leaf area, dried slice leaf/ha, grade index and crop index obtained from fetilizer experiment on three Virginia tobacco lines at Pekuwon Experimental Garden Bojonegoro, from May to October 2002. The results of this path analysis showed that crop index was strongly affected by dried slice leaf with path coeficient poi = 1.03367 and patial determination coefficient 102%. It was indicated that dried slice leaf was strongly affected by seventh leaf area with path coefficient p,n- 0.85257 and dried slice leaf strongly variable affected the crop index with path coeficient poi= 0.95639, while the grade index had little effect on crop index with path coefficient poi= 0.12316. The path analysis between leaf nicotine content and ive variables above was unfit with residual path coeficient pou= 0.6827, it was higher than each path coefficient of the orther variables. The dried slice leaf was the main independent variable affecting the crops index, so that selling of fresh tobacco leaves by farmers is not recomended.Key words : Nicotiana tabacum, Virginia tobacco, path analysis, leaf number, leaf area, crop index, grade index, nicotine content, dried slice leaf

Produksi rokok di Indonesia mcngarah ke rokok ringan sehingga kebutuhan tembakau bermutu baik dan ingan meningkat. Bahan baku utama yang semakin banyak dibutuhkan adalah tembakau madura. Untuk memperbaiki mutu dan mengurangi kadar nikotinnya, tembakau madura disilangkan dengan tembakau oriental. Sebanyak 9 galur harapan telah diperoleh dan diuji multilokasi bcrsama Prancak-95 sebagai pembanding. Pada tahun 2002 pengujian dilaksanakan di (1) Palalang 1 dan (2) Bajang, Kecamatan Pakong, Kabupaten Pamekasan seta (3) Guluk-guluk, Kecamatan Guluk-guluk, Kabupaten Sumenep. Pada tahun 2003 pengujian dilanjutkan di (1) Palalang 2, Kecamatan Pakong, Kabupaten Pamekasan seta (2) Bakeong dan (3) Por-dapor, Kecamatan Guluk-guluk, Kabupaten Sumenep. Pengujian di setiap lokasi menggunakan rancangan acak kelompok dengan tiga ulangan. Data dari semua percobaan dianalisis menggunakan program MSTAT. Anova menggunakan model 2 tahun, setiap tahun lokasi bcrubah. Analisis stabilitas'menggunakan mctode F.bcrhat dan Russell (1966). Tidak ada interaksi antara genotipe dengan lahun atau lokasi. Galur yang mempunyai nikotin lebih rendah dari Prancak-95 adalah 90/1 (2%) dan 93/2 (1.76%), masing-masing berkurang 13 dan 24% dai Prancak-95. Kedua galur tersebut stabil dan beradaptasi luas, galur 93/2 potensi hasilnya 0.892 ton/ha atau meningkat 11% dari Prancak-95, sedangkan 90/1 potensinya 0.798 ton/ha.Kata kunci: Tembakau, tembakau madura, uji multilokasi, nikotin rendah, Madura ABSTRACT Multilocation test ofpromising madura tobacco linesThe production of Indonesian cigaretes tends to the production of mild cigarete, so that the demand for higher quality and lighter tobacco increases. The demand for madura tobacco as the main raw mateial also increases. To improve its quality and to reduce its nicotine content, madura tobacco was crossed to oriental tobacco. Nine promising lines were produced and tested at multilocation together with Prancak-95 as a control. The multilocation tests were conducted in 2002 in (1) Palalang 1 and (2) Bajang, Pakong Distict, Pamekasan Regency, and in (3) Guluk-guluk, Guluk-guluk Distict, Sumenep Regency. In 2003 the tests were continued in (1) Palalang 2, Pakong District, Pamekasan Regency ; (2) Bakeong and (3) Por-dapor, Guluk-guluk District, Sumenep Regency. The tests in each location used a randomized block design with three replications. Data collected from all tests were analyzed using MSTAT Program. Anova was itted to model for 2 year tests, each year the location was changed. F.bcrhart and Russell method (1966) was used for stability analysis. There was no interaction between genotype and the year as well as the location. The tobacco lines that had lower nicotine content than Prancak-95 were 90/1 (2%) and 93/2 (1.76%). Their nicotine contents were lower than that of Prancak 95 by 13% and 24% respectively. The two lines were stable and broad adapted. Line 93/2 had yield potency 0.892 ton/ha higher by 1 1% than that of Pancak-95, while the yield potency of line 90/1 was 0.798 ton/ha.Key words: Tobacco, madura tobacco, multilocation test, low nicotine, Madur
