'Brasileirinha': an ornamental bicolor squash (Cucurbita moschata) cultivar for immature fruit consumption

'Brasileirinha' is a squash (Cucurbita moschata) cultivar developed by Embrapa Vegetable Crops, with a appealing ornamental appearance and carotenoid composition of its fruits might provide raw material for the development of value-added products targeting new market niches. This cultivar is an F7 line obtained by conventional crosses between an accession with bicolor fruits, more likely due to the presence of an allele of the B gene, and cultivar Mocinha (with uniform green fruits). The presence of bicolor fruits is the peculiar characteristic of cultivar Brasileirinha. The proximal portion of the fruit skin has a bright yellow color, while the distal portion has an intense green color. The fruit flesh has a uniform light yellow (cream) color when harvested at the immature stage, whereas at the ripe stage its flesh is orange. Beta-carotene and lutein are the predominant carotenoids at the immature stage. In fully mature fruits, the predominant pigments are beta-carotene and alfa-carotene (two pro-vitamin A carotenoids), with average values reaching 243 mg g-1. Cultivar Brasileirinha displayed good levels of field resistance to distinct powdery mildew (Podosphaera xanthii) races. This cultivar is recommended for consumption at immature fruit stage, for ornamental purposes (all fruit stages) and it might also be suitable for pickles (young fruits). Cultivar Brasileirinha might be used in all the traditional squash-producing areas of Brazil. The cropping system recommended for this cultivar is the ordinarily used for squash production.
