“…Riceberry combines the desirable features of two prominent rice varieties, one a local, non-glutinous purple rice and the other an aromatic white jasmine rice (Waiyawuththanapoom et al, 2015;Gene Discovery Rice and Rice Science Center, 2017). Two improved pigmented varieties 2 www.irri.org/international-rice-genebank (the red rice "Rubi" and the black rice "Onix") have been released in Brazil (Wickert et al, 2014).…”

Improving the nutritional quality of rice grains through modulation of bioactive compounds and micronutrients represents an efficient means of addressing nutritional security in societies which depend heavily on rice as a staple food. White rice makes a major contribution to the calorific intake of Asian and African populations, but its nutritional quality is poor compared to that of pigmented (black, purple, red orange, or brown) variants. The compounds responsible for these color variations are the flavonoids anthocyanin and proanthocyanidin, which are known to have nutritional value. The rapid progress made in the technologies underlying genome sequencing, the analysis of gene expression and the acquisition of global 'omics data, genetics of grain pigmentation has created novel opportunities for applying molecular breeding to improve the nutritional value and productivity of pigmented rice. This review provides an update on the nutritional value and health benefits of pigmented rice grain, taking advantage of both indigenous and modern knowledge, while also describing the current approaches taken to deciphering the genetic basis of pigmentation.

“…Some people prefer pigmented (red or black) rice grains due to their taste, texture, aroma, and ceremonial or medicinal value (Sweeney et al, 2006 ). Wickert et al ( 2014 ) bred the cultivars “SCS119 Rubi” and “SCS120 Onix,” with red and black grains, respectively, for specialty rice markets in Brazil. These cultivars had the same protein, lipid, carbohydrate, mineral, and fiber content as white rice, but contained higher levels of anthocyanins and phenolics than their ancestor cultivars.…”

Phenylpropanoids are a diverse chemical class with immense health benefits that are biosynthesized from the aromatic amino acid L-phenylalanine. This article reviews the progress for accessing variation in phenylpropanoids in germplasm collections, the genetic and molecular basis of phenylpropanoid biosynthesis, and the development of cultivars dense in seed-phenylpropanoids. Progress is also reviewed on high-throughput assays, factors that influence phenylpropanoids, the site of phenylpropanoids accumulation in seed, Genotype × Environment interactions, and on consumer attitudes for the acceptance of staple foods rich in phenylpropanoids. A paradigm shift was noted in barley, maize, rice, sorghum, soybean, and wheat, wherein cultivars rich in phenylpropanoids are grown in Europe and North and Central America. Studies have highlighted some biological constraints that need to be addressed for development of high-yielding cultivars that are rich in phenylpropanoids. Genomics-assisted breeding is expected to facilitate rapid introgression into improved genetic backgrounds by minimizing linkage drag. More research is needed to systematically characterize germplasm pools for assessing variation to support crop genetic enhancement, and assess consumer attitudes to foods rich in phenylpropanoids.

“…Ambos os cultivares são pertencentes à espécie Oryza sativa. Os cultivares possuem expectativa de produtividade diferenciadas, a produtividade média do SCS119 Rubi é de 7.900 kg por hectare e o SCS120 Ônix tem alcançado produtividades médias de apenas 5.500 kg por hectare (WICKERT et al, 2014).…”

Resumo: O potássio (K) estimula o aproveitamento do nitrogênio (N) pelas plantas possibilitando que as produtividades sejam maiores. Objetivou-se avaliar o efeito da aplicação de N e K sobre o crescimento, produção de grãos e concentrações de N e K nas folhas dos cultivares SCS119 Rubi -arroz de pericarpo vermelho e SCS120 Ônix -arroz de pericarpo preto. O experimento foi realizado em casa de vegetação, em vasos com 9 kg de amostras de solo da camada de 0-0,2m de um Gleissolo Háplico. Nos dois cultivares de tipos especiais de arroz foram testadas: omissão individual e completa (0%) de N e K e aplicação combinada destes nutrientes, em esquema fatorial 2x2. As quatro combinações de N e K, em mg dm -3 foram: 0-0; 0-60; 180-0; 180-60. O N e o K foram fornecidos como ureia e cloreto de potássio, respectivamente. O delineamento experimental foi de blocos ao acaso, com 3 repetições. A adição de K à adubação nitrogenada para o SCS119 Rubi foi fundamental para maximizar o perfilhamento, o crescimento da parte aérea na fase vegetativa do arroz e a produção de grãos. Alta dose de N com a omissão da aplicação de K ocasionou desequilíbrio nutricional das plantas evidenciado pelas altas concentrações de N no tecido vegetal. Os cultivares de arroz diferiram quanto ao aproveitamento do N e K para o perfilhamento e crescimento sendo considerado responsivo o SCS119 Rubi e não responsivo o SCS120 Ônix. Palavras-chave:Arroz vermelho, arroz preto, adubação nitrogenada e potássica, perfilhamento, estado nutricional.Abstract: Potassium (K) stimulates the efficient use of nitrogen by plants increasing crop yield. The aim was to evaluate the effect of N and K on the growth, grain production and N and K concentration on leaves of cultivars SCS119 Rubi -red pericarp rice and SCS120 Onix -black pericarp rice. The experiment was performed in a greenhouse using pots with 9 kg of soil samples at 0-0.2 m depth of Haplic Gleysol. In two cultivars of special types of rice were tested: individual and complete omission (0%) of N and K and combined application of these nutrients, in a 2x2 factorial design. The four combinations of N and K, in mg dm -3 were: 0-0; 0-60; 180-0; 180-60. N and K were provided as urea and potassium chloride, respectively. The experimental design was randomized blocks, with three repetitions. The addition of K to N fertilization to SCS119 Rubi was essential to maximize tillering, the shoot growth in the vegetative stage of rice and grain production. High dose of N with the omission of the K application caused imbalance nutritional in plants evidenced by high concentrations of N in plant tissue. The rice cultivars differed on the use of N and K for tillering and growth being considered responsive the SCS119 Rubi and unresponsive the SCS120 Onix.
