Narrative
`Bettergreen' is homozygous for a newly discovered gene that conditions a unique green cotyledon trait. `Bettergreen' can be harvested near-dry seed maturity without loss of the seed's fresh green color. Except for the green cotyledon trait and slightly greener foliage of mature plants, the `Bettergreen' phenotype is similar to that of `Carolina Cream'. `Bettergreen' is a small-seeded (11.5 g/100 dry peas, 22 g/100 fresh peas), cream-type southernpea. The plants have a medium, bushy growth habit. A typical pod is slightly curved, 15 cm long, and contains 12 to 14 peas. Pods are green when immature, green with a distinct purple shading at optimum green-shell maturity, and pale tan or straw colored when dry. Fresh peas are ovate to reniform in shape; dried peas have a smooth seed coat. Seed coats and cotyledons of field-grown `Bettergreen' peas harvested at dry-stage maturity are light olive (Munsell color rating: 7.5 Y 7/6). In comparison, seed coats and cotyledons of `Carolina Cream' peas harvested at similar maturity have no green (Munsell color rating: 2.5 Y 8/4). `Bettergreen' should exhibit the same resistances to the cowpea curculio (Chalcodermus aeneus Boehman), cercospora leaf spot (Cercospora cruenta Sacc), southern blight (Sclerotium rolfsii Sacc.), rust (Uromyces phaseoli (Pers.) Wint. var. vignae (Barcl.) Arth.), and powdery mildew (Erysiphe polygoni DC ex St. Amans) and the same tolerances to seedling diseases as `Carolina Cream'. `Bettergreen' is susceptible to root-knot nematodes (Meloidogyne spp.), as is `Carolina Cream'. [NOTE: Subsequent research demonstrated that the green cotyledon trait is conditioned by a single recessive gene designated green cotyledon (symbolized gc). (R. L. Fery and P. D. Dukes, J. Amer. Soc. Hort. Sci.119:1054-1056 (1994))]

Pedigree
Date released:
30 Apr 1991
Description:
`Bettergreen' was derived from a single mutant plant discovered in a 1986 field planting of the cultivar Carolina Cream. `Carolina Cream' is a well-adapted, cream-type cultivar that was released by the USDA in 1982 [R. L. Fery and P. D. Dukes, HortScience 19:456-457 (1984)]. `Carolina Cream' was derived from the cross Ala. 963.8 x `Floricream'
