1. Patterns recognition methods to study genotypic similarity in flood-irrigated rice
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t

4. BRS 901 and BRS 902: red rice cultivars bred for Brazil
Abstract BRS 901 and BRS 902 are red pericarp rice cultivars developed by Embrapa for irrigated and rainfed lowland production systems in Brazil. These cultivars have medium and early maturation cycles, respectively, and both have high grain yield potential, good lodging tolerance and short to medium length grains.

5. BRSMG Alterosa: Rice cultivar for lowland cultivation in Minas Gerais
Abstract The lowland rice breeding program, developed in Minas Gerais state, has as basic objective to release new commercial cultivars. In this way, this program is making available a new cultivar named BRSMG Alterosa, which has as main characteristics: high grain yield, high tillering, medium cicle, diseases tolerance and high grain quality. It was recomme

6. Development of Oryzophagus oryzae (Costa Lima) in rice cultivars
RESUMO Cultivares resistentes a insetos são essenciais à melhoria do manejo de pragas como Oryzophagus oryzae (Coleoptera: Curculionidae), altamente prejudicial à cultura do arroz irrigado por inundação. O grau de benefício, porém, depende do tipo de resistência. Objetivou-se avaliar cultivares de arroz quanto à resistência a O. oryzae, inferindo

7. Control of plant height by 24 alleles at 12 quantitative trait loci in rice
Abstract Plant height (PH) is controlled by quantitative trait loci (QTLs) in rice. In the present study, a recombinant inbred line population developed by crossing two rice cultivars, Lemont and Yangdao4, was grown in eight environments for QTL analysis. Multiple interval mapping detected 53 PH-QTLs, 39 of which clustered at 12 chromosome regions/putative l

9. Spatial and temporal evolution of imidazolinone-resitant red rice in 'Clearfield' rice cultivations
Resumo: O objetivo deste trabalho foi avaliar a distribuição de populações de arroz-vermelho (Oryza sativa) resistente às imidazolinonas (R-IMI), a frequência dos alelos que conferem resistência às IMI, e a adoção de práticas agronômicas aplicadas ao controle do arroz-vermelho, em estações de cultivo e regiões produtoras de arroz do Estado do

10. Effect of rice variety and milling fraction on the starch gelatinization and rheological properties of rice milk
Abstract This study aimed to investigate the rheological properties of rice milk produced from raw rice including rice varieties and milling fractions. Rice milk was prepared from two rice varieties, which were Arhent (long grain) and Bengal (medium grain) using brown, head and broken fractions of the two cultivars used. Gelatinization temperatures for each

11. Assessment of genetic variation of 15 Thai elite rice cultivars using InDel markers
Abstract Many elite rice varieties have been developed in the last decades by Thai rice breeders. No information about the genetic gene pool of these elite rice varieties is available. This study evaluated the genetic relationship of 15 elite Thai rice cultivars using Indel markers. Of the 133 markers screened, 44 were polymorphic. The PIC scores ranged from
