A collection of 30 varieties of tobacco (Nicotiana tabacum) with growth characteristics similar to pale yellow Tobacco Introduction 1372 was studied for chlorophyll content, ripening characteristics, and agronomic and chemical properties. The yellow tobaccos had a higher proportion of leaves removed in the first and second harvests than did flue-cured varieties indicating their tendencies toward early maturation. Chlorophyll content did not seem to be related to starch or sugar content and was only slightly related to yield. The entries varied from each other in all characters measured and most entries were below the flue-cured checks in yield and value characters. The total chlorophyll content for the yellow tobaccos was below that of the flue-cured checks.
