CTH14 is the second flue-cured tobacco (Nicotiana tabacum L.) hybrid recommended for commercial release in Canada. The yield of CTH14 is significantly superior to that of CT157, one of two check varieties, while the grade index is superior to the other check variety Delgold. As a result, the economic return of CTH14 is significantly superior to both check varieties. CTH14 has uniform growth both in the greenhouse and in the field. Leaf quality traits of CTH14 are far superior to Delgold, as well as most other commercial varieties in Ontario.Key words: Nicotiana tabacum L., tobacco, hybrid, male sterility, black root rot, cultivar description

CT652 is a flue-cured tobacco (Nicotiana tabacum L.) cultivar with good yield potential, high grade index and considerably higher gross returns than the check varieties Delgold and CT157. It was derived from a cross between the Canadian cultivar Delfield and an advanced breeding line, 95EA57-1. Key words: Nicotiana tabacum L., tobacco, cultivar description

In Ontario, flue-cured tobacco (Nicotiana tabacum L.) growers routinely fumigate their soils to control root-lesion nematodes (Pratylenchus penetrans Cobb). Studies suggest that planting pearl millet (Pennisetum glaucum L.) as a rotation crop may control the nematodes; winter rye (Secale cereale L.), the crop commonly grown in rotation with tobacco, is susceptible to the nematodes. In 2002, plots of forage millet (var. CFPM 101), grain millet (var. CGPMH-1) and winter rye were established at three sites and in 2003, tobacco was grown at these sites in non-fumigated plots where the rotation crops grew, except for a winter rye/fumigation treatment. The goal was to evaluate P. penetrans populations and tobacco yield and quality in the millet rotations relative to the traditional rye-fumigation system. In 2002, initial P. penetrans populations assessed in the spring were similar for all treatments; however, the final populations and consequently the ratios of final populations/initial populations (Pf/Pi) consistently differed among treatments. The Pf/Pi ratios ranged from 0.07 to 0.79 for forage millet, from 0.18 to 0.94 for grain millet and from 2.33 to 21.65 for rye. In 2003, P. penetrans populations in tobacco plots previously cropped to either type of millet were comparable with those detected in fumigated winter rye plots. Compared with tobacco following rye without fumigation, tobacco yield was 14 to 51% higher following rye with fumigation, 19 to 70% higher following forage millet and 18 to 65% higher following grain millet. Grade index was unaffected. Results indicate that pearl millet offers an alternative to fumigants for the suppression of P. penetrans population and provides equivalent gross returns.

Response of cigar tobacco (Nicotiana tabacum L.) in morphological, agronomic and chemical characteristics to date of planting and planting distance was studied during 1971–73. A cultivar and a breeding line of cigar tobacco were transplanted outdoors on 26 May, 9 (or 12) June and 23 June. The tobacco was spaced 36, 41 and 46 cm in rows that were 97 cm apart. The best results were obtained when cigar tobacco was transplanted not later than 9 June, and the plants were spaced 41 cm in the rows that were 97 cm apart. The highest number of leaves per plant, cured-leaf yield, percentage of nicotine and total alkaloids were obtained from the tobacco transplanted on the first or second date in 3 yr. In 2 yr, the later tobacco had the tallest plants, the largest leaves, the highest percent filler leaf, grade and crop index. Earlier-transplanted tobacco was harvested earlier, although the period to flower decreased with later date of planting. On the average, the tobacco spaced 41 cm was taller and had a shorter period to flower, and higher yield and crop index than that spaced 36 cm or 46 cm. Grade index, percent filler leaf, nicotine and total alkaloids were affected significantly by the distance in 1 yr only.

CTH144 is a new flue-cured tobacco (Nicotiana tabacum L.) hybrid recommended for commercial release in Canada. The cured leaf quality of CTH144 was superior to both check varieties Delgold and CT157. The yield potential of CTH144 was intermediate compared with the checks. As a result, the economic return of CTH144 is superior to both check varieties. CTH144 has resistance to Tobacco Mosaic Virus. CTH144 is adapted to the tobacco-growing areas of southwestern Ontario.

A diallel cross of four cigar cultivars and one pipe tobacco (Nicotiana tabacum L.) cultivar was analyzed for the following parameters: grade index, yield, crop revenue or index, percentage of nicotine, percentage of total alkaloids, and susceptability to pole rot. The experiment was performed over 3 years. Analysis was done for general combining ability and specific combining ability. General combining ability was greater than specific combining ability for all variables although significant specific combining ability effects were also present for all parameters with the exception of nicotine and total alkaloids. Reciprocal effects were completely absent. The line Pennbel 69 showed a positive general combining ability effect for yield, crop index, and infestation by pole rot and a high negative general combining ability effect for grade index and percentage of nicotine and total alkaloids. Petit Havane showed a complete reverse of general combining ability effects for these parameters while the other three cultivars were intermediate. High positive specific combining ability effects for grade index, yield, and crop index and high negative specific combining ability effects for the percentage of pole rot were shown by crosses of Pennbel 69.

Tipe tanah ketiga desa tersebutberturut-turut adalah lempung, liat, dan lempung berdebu. Pengujiandilakukan pada tiga periode tanam tahun 2007 dan 2008. Hasil penelitianmenunjukkan bahwa tipe tanah berpengaruh terhadap hasil dan indekstanaman, yang terbaik adalah tanah lempung seperti di Desa Rejuno.Berdasarkan hasil, indeks tanaman dan penilaian organoleptik, varietasyang terbaik adalah Zichna, hasilnya rata-rata 2,213 t/ha dan indekstanaman 91,66. Varietas tersebut menghasilkan sensasi iritasi dan impakrendah dan aroma sangat baik. Pada urutan berikutnya adalah varietasXanthi Yaka, hasilnya 1,742 t/ha, indeks tanaman 78,27. Berdasarkan hasilpenelitian tersebut maka kedua varietas tembakau oriental tersebut jugasesuai untuk rokok kretek di Indonesia.

Soil types of the three villages wereloam, clay, and silt loam, respectively. The tests were carried out for threeplanting series in 2007 and 2008. Research result showed that soil typesaffected several agronomic characters as well as yield and crop indices.The most suitable soil was silt loam as in Rejuno village. According toyield, crop index, and organoleptic evaluation, Zichna variety was the bestwith yield potential and crop index of 2.213 t/ha and 91.66.Organoleptically, the variety was low irritation and sensation impact andvery good in aroma. The second best variety was Xanthi Yaka with yieldpotential and crop index of 1.742 t/ha and 78.27. This research revealedthat Zichna and Xanthi Yaka varieties were suitable as raw material forclove cigarette. In addition, these two varieties were also well suited to begrown in Indonesia, especially on loamy and sandy soils with large amountof lime.</p><p>Key words : Nicotiana tabacum L., oriental tobacco, variety, Indonesia</p>
