Morphological and agronomic variability in Cuphea viscosissima Jacq.

Cuphea viscosissima has been proposed as a possible domestic source of medium-chain triglycerides, particularly capric [decanoic] acid (10:0), a 10-carbon saturated fatty acid. Domestication of this species is dependent upon obtaining variability for the constraining characters necessary to make this wild species into an economic crop. This paper reports the variability found among 40 accessions recently collected from the central US, plus three other accessions, all part of the Cuphea germplasm collection at the North Central Regional Plant Introduction Station. Morphological variability was found to be very limited. However, significant differences were found in plant mass, plant height, postharvest seed dormancy, seed shattering, 100-seed weight, seed yield, oil content and the amounts of caprylic [octanoic] (8:0) and capric acid. The degree of natural variation in seed size, seed yield, oil percentage and fatty acids could be exploited to produce improved cultivars.
