Calidad molinera de las variedades de arroz SD20a y payara 1FL, y su resistencia a Sitophilus oryzae (L.) y Rhyzopertha dominica (F.)
Agroindustry requires rice varieties that allow obtaining whole grains during its processing and also to resist insect attac-ks.

| Summary: | Agroindustry requires rice varieties that allow obtaining whole grains during its processing and also to resist insect attac-ks. In this study was determined milling quality of varieties SD20A and Payara 1FL, and their resistance to Sitophilus oryzae (L.) and Rhyzopertha dominica (F.). In the first pha-se, the whiteness ratio (WR) and grain yield in a mill (GY) were calculated for both varieties, while in the second phase, those were through the attack of S. oryzae and R. dominica, in paddy and milled rice condition, during three months. The resistance was interpreted based on the number of adults emerged at the end of the experiment. There were statistical differences (p< 0.01) between WR and GY of rice varieties SD20A (32.40 ± 1.87°Kett and 44.40 ± 2.55%) and Payara 1FL (35.90 ± 0.63°Kett and 48.20 ± 1.69%). Adult emerged numbers of S. oryzae and R. dominica was different between SD20A and Payara 1FL (p< 0.01), being higher in milled rice than those registered on paddy rice. The amount of adult of R. dominica was always higher than S. oryzae, except for Payara 1FL milled rice in where no significative difference (p> 0.01). Results showed that Payara 1FL had a higher yield in the mill than SD20A, and higher resistance to S. oryzae attacks than to R. dominica. |
