Diversity in grain physico-chemical characteristics of West African rice, including NERICA genotypes, as compared to cultivars from the United States of America

摘要: Landraces from West Africa (WA), NERICA progenies derived crosses between Oryza sativa and glaberrima, improved O. lines Rice Center were introduced to the Beaumont Research in Texas, United States of America (USA) (29o57’ N 94o30’ W) for in-situ evaluation characterization. Milled samples rice produced Cote d’Ivoire (CI) (7.5o - 8.5o 4.5o W 5.5o also chemical analysis. RVA profiles showed that Jaya has unusually strong paste viscosity features. Apparent Amylose content varied 15% Khao Dawk Mali 105 originally Thailand, 26% CG 14, an glaberrima type. WAB 56-104, variety Center, had longest cooking time 24 minutes. can be compared Dixiebelle, a USA grown commercially under contract canning processing industries. Total milling yield 78% Gnanle Gnan-Man, landrace WA, 70% check Saber. Sierra, check, highest value 2-AP (1258 ng/g), followed by Bakue Danane Cocote, both CI. Comparing WA CI with those pasting parameters not generally strongly affected environment. The variable most environment was setback which predicts hardness cooked rice. Diverse sources grain quality traits found germplasm use USA.
