3 1 INTRODUCTIONI American flue-cured tobacco is known worldwide for its unique smoking qualities. The Flue-Cured Tobacco Minimum Standards Program was initiated in 1964 to ensure that released varieties have acceptable agronomic, physical, chemical and smoke characteristics. The North Carolina Official Variety Trials for flue-cured tobacco are conducted annually to provide information to growers and the tobacco industry on performance of varieties that have passed the Minimum Standards Program and may be available to the growers in North Carolina. Breeding lines are also included as a first step in advancing these potential varieties through the Minimum Standards Program. The Acreage-Poundage Program tends to encourage quality of flue-cured tobacco by limiting the production in terms of pounds per acre. Varieties contribute substantially to leaf quality and should be carefully selected by the grower. Therefore, this bulletin has been written with emphasis on the quality of various varieties that are available to tobacco growers. Data are presented for three, two years and one year over all locations and by location in this bulletin. Growers are cautioned to examine data from two and three-year tables prior to selection of a variety to grow on their farms. They are also encouraged to ITechnical assistance by Ken Barnes and Carey Parsons are gratefully acknowledged.

4 2 grow a small acreage of the new variety rather than the whole crop at once. The Official Variety Trials consist of small replicated plots located on five research stations. The Regional Minimum standards Program evaluates potential new varieties by the Regional Small Plot Test and Regional Farm Test. Results of these tests are reported separately in the Flue-Cured Variety Evaluation Committee Report. EXPENTALPROCEDURES Official Variety Test Twenty-five released varieties and nineteen experimental lines were tested at five locations (Figure 1) in The Official Variety Tests were conducted on disease-free soil insofar as possible. The experimental locations are as follows: Border Belt Tobacco Research station, Whiteville, N.C., representing the Border Belt. Lower Coastal Plain Tobacco Research station, Kinston, N.C., representing the Eastern Belt. Upper Coastal Plain Research station, Rocky Mount, N.C., representing the Eastern Belt. Oxford Tobacco Research station, Oxford, N.C., representing the Middle Belt. Upper Piedmont Research Station, Reidsville, N.C. representing the Old Belt.

At transplanting, the plants were individually selected for uniformity and planted into one-row plots, each of which consisted of twenty competitive plants spaced 22 or 24 inches apart, depending upon locations. The row spacing was four feet at all locations except Reidsville which was 3.75 feet. Additional cultural practices are shown in Table 1. Each

6 4 entry was replicated three times in a randomized, complete block design at eagh location. 2 After topping, all entries were treated with commercial contact and systemic sucker control chemicals. Individual plots were harvested according to degree of maturity and primings were tagged and kept separate throughout curing, sorting, and grading. Performance data were collected on yield, quality, agronomic characteristics, disease resistance,3 and physical quality traits. Data on agronomic characteristics were collected in the field. Dollar value per hundredweight and grade indices are shown to emphasize quality differences among the varieties. Dollar value per hundredweight was calculated from a two-year average price paid per pound on the flue-cured market for a particular government grade. After the tobacco was sorted into lots, a Federal Tobacco Inspector assigned an appropriate government grade to each lot from each plot. The average dollar value per hundredweight was then computed based on a weighted average by stalk position. Each entry was rated also with a grade index ranging from 1 to 100. This index was calculated by assigning a numerical value to each government grade of each entry. An average grade index value was then obtained for each entry in the same manner as dollar per hundredweight. Grades N2 and B1L represent the practical extremes with values of 1 and 100 assigned to these respective grades. The 2Statistical analyses were performed by Mrs. Her assistance is gratefully acknowledged. Sandra Donaghy. 3Drs. David Shew, Charles Main, and Tom Melton of the Plant Pathology Department and Dr. Verne Sisson of the Department of Crop Science cooperated on the tests for disease reaction. Their assistance is gratefully acknowledged.

7 data utilized a revised version of the grade index as originally developed by E. Wernsman and E. Price (1975). Seasonal Conditions: Transplanting was delayed in the Border and Eastern Belts but on time in the Middle and Old Belts (Table 1). Rainfall was below normal until June when it was above normal at most locations (see accompanying graphs). The excessive rains resulted in less than desirable tobacco plants by topping time at most locations. Yields and quality were low as a result of the June rains. RESULTS AND DISCUSSION The data presented in Tables 2 and 3 summarize how varieties performed over a period of years at various locations. These tables give a general indication of the stability of the varieties since they include performance data over many locations and years. In Table 2, varieties that were common in 1993, 1994, and 1995 are compared for a number of agronomic and chemical characteristics. Two-year data are presented in Table 3 for 1994 and Table 4 shows the cumulative rate of harvest, approximate number of leaves/acre handled, and yield of cured leaf harvested by the end of the third priming for selected commercial varieties at Whiteville for All tobacco was harvested and graded ripe, thus, this information can be used to ascertain the relative rate of ripening among varieties. The number of leaves/acre handled should indicate barn space requirements and labor requirements! Yield should be considered with number of leaves handled as well as

8 6 leaf ripening rate to choose those varieties that will maximize efficiency of the grower's tobacco operation. Information on disease resistance is presented in Table 5. Data were collected on black shank, bacterial wilt, brown spot, root knot nematodes and mosaic. A relative rating of the level of resistance to black shank and bacterial wilt is given for each variety along with a numerical rating where lower numbers indicate higher resistance. Root knot and mosaic resistance are recorded as resistant or segregating. These data were furnished by Drs. Tom Melton, Verne Sisson, Charlie Main and David Shew. The average performance across four locations in 1995 is shown in Table 6. NC 27NF and NC 37NF are nonflowering genotypes and should be topped at harvestable leaves. Days from transplanting to topping are reported in the days to flower column for these two varieties. Individual location data are presented in Tables Table 12 lists the pedigrees, year of release, and the developer of commercial varieties in the 1995 Official Tobacco Variety Tests.
