Physical, chemical and industrial quality in upland rice genotype

Abstract: For the recomendation of the new rice cultivars, it is necessary that these have the physical, chemical and industrial standard of quality required by the market. The lines must have long thin classification, intermediate amylose content and gelatinization temperature, and high percentage of whole grains. This study aimed to evaluate the quality of grains in the elite lines of the UFLA Rice Breeding Program. The experiments were carried out in the experimental area of the Department of Agriculture, UFLA/MG in the 2013/14 and 2014/15 seasons, and in the Epamig experimental farm, Sertaozinho experimental field, in Patos de Minas/MG, in the 2013/15 season. After harvest evaluated the traits: yield (kg.ha -1 ), percentage of whole grains, length/thickness ratio (mm), chalky grains percentage, amylose content (%) and gelatinization temperature (notes) were processed and determined. For most traits evaluated, the genotypes x environments interaction was significant, indicating differences in the behavior of lines in different environments. The lines showed thin long grain classification, intermediate amylose content and medium to low gelatinization temperature. CMG 2097 genotype is outstanding, which has a high percentage of whole grains, high yield potential and ideal phenotypic traits for high quality of grain.
