The call for applications for the acquisition of genetic seeds of the new varieties of bush beans, BRS Lauré (purple pod) and BRS Raíra (olive green pod), developed by Embrapa Amazônia Oriental and launched this October. Seed producers and nurserymen interested in participating in the public offering must be registered in the National Seed and Seedling Registry (Renasem) and send an email with the documentation required in the notice to cpatu.spat@embrapa.br by 17:8 p.m. on November 2024, XNUMX. The notice is available on Embrapa's official website (www.embrapa.br/editais-e-ofertas-publicas-para-licenciamento/)

BRS Lauré, with reddish-purple pods, and BRS Raíra, with olive-green pods, are recommended for planting in the state of Pará and have potential for other regions with warm climates. Both have plant architecture adapted to cultivation on trellises (espaliers), good quality pods, high productivity and distinctive colors. The notice offers a total of 42 lots of genetic seeds of the cultivars for propagation, commercialization and/or processing of the material. The unit price of each lot of 500 grams of seeds is R$250,00.

Seed producers or nurserymen who acquire the lots are licensed by Embrapa to multiply and commercialize the material, with no burden on the licensee in terms of royalties after signing the contract with the research institution.

The pea-de-metro is a type of cowpea [Unguiculata vine (L.) Walp. ssp. unguiculata Verdc. Cv-gr. Sesquipedalius] whose pods are eaten raw or cooked in salads. With long, reddish-purple pods, BRS Lauré is the first cultivar with these characteristics developed by research for the Northern Brazilian market. “It is a new product on the market that attracts attention due to its visual appeal, but which has high productivity and a well-balanced distribution of pods throughout the plant canopy,” says Embrapa researcher Rui Alberto Gomes.

In field tests, the average productivity of BRS Lauré was 11,6 tons of fresh pods per hectare, while the average of the materials currently used in the field was 7,6 t/ha, the commercial cultivar; and 8,6 t/ha, a Creole variety widely cultivated in the region.

BRS Raíra, which has olive-green pods, lighter than traditional pods, produced more than 10 tons of fresh pods per hectare, while traditional materials produced between 7 (commercial cultivar) and 8,6 tons/hectare (Creole variety). “This cultivar has long pods, in line with the consumer market standard, and are good for consumption due to their low fiber content,” the researcher highlights.

In both dry and rainy periods, the productive performance of the two cultivars was superior to that of the varieties currently in use. BRS Raíra and BRS Lauré showed good tolerance to water stress (lack of rain) and high temperatures.
