Abstract
'Brasileirinha' é uma cultivar de abóbora (Cucurbita moschata) com frutos bicolores que foi desenvolvida com o objetivo de disponibilizar um produto diferenciado devido ao aspecto ornamental e a composição nutricional de seus frutos. Esta cultivar foi selecionada na geração F7, sendo obtida via cruzamentos convencionais entre um acesso de frutos bicolores, provavelmente devido à presença de um alelo do gene B, e a cultivar Mocinha (com frutos imaturos de cor verde uniforme). A característica peculiar da cultivar Brasileirinha é a produção de frutos com casca apresentando uma marcante coloração bicolor (coloração amarela na região proximal e verde na posição distal dos frutos). A polpa apresenta coloração amarela-esverdeada em frutos colhidos imaturos e, à medida que o fruto amadurece, intensifica-se uma coloração alaranjada. Beta-caroteno e luteína são os principais carotenóides presentes em frutos para consumo verde. Em frutos em completo estádio de maturação (polpa laranja intensa) verifica-se a acumulação de beta-caroteno e alfa-caroteno (precursores da vitamina A) em torno de 243 mg g-1. A cultivar Brasileirinha tem apresentado boa resistência de campo a diferentes raças de oídio (Podosphaera xanthii). Esta cultivar é preferencialmente recomendada para consumo como abobrinha verde (no estádio de fruto imaturo) e para fins ornamentais (frutos em todos os estádios). Uma opção é o uso de frutos jovens em conservas. A cultivar Brasileirinha é recomendada para plantio em todas as tradicionais regiões produtoras do país. O sistema de produção para esta cultivar tem sido o mesmo adotado para outros tipos de abóboras.
'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.
