“…In the more near term, the Canadian flue‐cured tobacco cultivar Delgold might be a valuable source of alleles to permit further increases in yield while keeping PTA at acceptable levels. Delgold has N. rustica , a high‐alkaloid species, in its pedigree (Pandeya and White, 1984), but it is currently unknown if any N. rustica germplasm is actually present in the genome of this cultivar.…”

“…Cultivars Hicks, K326, and NC 95 were selected as being representative of the U.S. flue‐cured germplasm base. The Canadian cultivar Delgold was selected because it has N. rustica L. (a high alkaloid Nicotiana species) in its pedigree and was derived from a breeding program emphasizing selection for increased PTA (Pandeya and White, 1984). TI 501, TI 216, TI 959, and TI 464 are accessions from the United States Nicotiana Germplasm Collection that were selected for high PTA per se on the basis of data from a one‐replicate field test reported by Sisson and Saunders (1982) TI 281, TI 648, TI 835, TI 859, TI 934, and TI 973 are germplasm accessions selected on the basis of high best‐possible estimates of total alkaloid production (TAP, kg ha −1 ) calculated using PTA and green leaf yield data publicly available from the website of the Germplasm Resources Information Network (http://www.ars-grin.gov).…”

Identification of Germplasm of Possible Value for Confronting an Unfavorable Inverse Genetic Correlation in Tobacco

To be commercially viable in the USA, a flue‐cured tobacco (Nicotiana tabacum L.) cultivar must be high‐yielding and also meet minimum requirements for percent total alkaloids (PTA). The negative correlation between yield and PTA complicates development of higher‐yielding cultivars with acceptable leaf chemistry, however. Identification and use of germplasm possessing alternative alleles positively affecting PTA could be an important component of strategies to develop commercially acceptable, higher‐yielding cultivars. Choice of donor germplasm should be done carefully, however, because yield modulates the phenotypic expression of PTA. Consequently, comparison of materials for genetic potential to accumulate alkaloids might best be done at common levels of yield. This investigation used manual control of leaf number to manipulate yield of fifteen diverse tobacco genotypes grown in a split‐plot design in two North Carolina environments. Within genotypes, the relationships between PTA and yield were found to be negative. Through statistical analyses, germplasm accessions TI 464 and TI 959 were found to exhibit the highest levels of PTA at given levels of yield in both environments. Data on N‐partitioning indicated that these genotypes may have increased genetic potential for utilizing accumulated N for alkaloid synthesis. Transfer of alleles from these genotypes to elite germplasm pools may facilitate development of higher‐yielding cultivars with acceptable PTA levels.

“…It was produced by pollinating plants of an elite cytoplasmic male-sterile line (derived from the breeding line 22M6) with the pollen of an advanced breeding line from the cross 93CV157-3/Delgold, made in 1998 at the Delhi Research Farm, in Ontario. 93CV157-3 is an experimental line and Delgold (Pandeya and White 1984) is a Canadian cultivar. The cytoplasmic male sterility of the female parent originated from Nicotiana suaveolens Lehm.…”

CTH8 is a new flue-cured tobacco (Nicotiana tabacum L.) hybrid recommended for commercial release in Canada. It has superior grade index compared to the check varieties Delgold and CT157, and its yield potential is intermediate between the two checks.

. 2003. Effect of the Nicotiana debneyi black root rot resistance gene on the yield and quality characteristics of flue-cured tobacco in Ontario. Can. J. Plant Sci. 83: 939-942. The effects of Nicotiana debneyi-derived resistance to black root rot disease were evaluated for yield, agronomic and quality traits by comparing the near isogenic cultivars AC Gayed (resistant) and Delgold (susceptible). Over 7 yr of trials the possession of resistance led to yields and economic returns that averaged 6 and 7% lower, respectively, than for the susceptible line. Les auteurs ont évalué les effets de la résistance de Nicotiana debneyi au pourridié noir sur le rendement, les paramètres agronomiques et la qualité du tabac en comparant les cultivars presque isogéniques AC Gayed (résistant) et Delgold (sensible). Au cours des sept années qu'ont duré les essais, les gènes de résistance ont entraîné une baisse moyenne du rendement et des recettes respectivement de 6 et de 7 % comparativement à la variété sensible.
