"This study had the objective of assessing test lines and rice cultivars, in relation to grain yield and other agronomic traits, under different cropping and irrigation management systems, in the Rio Branco lowlands, municipality of Cantá, Roraima State, Brazil. A randomized complete block design was used, with four replications. Nineteen test lines and six cultivars were assessed. Significant differences for most of the evaluated traits were observed. The highest grain yield was obtained under a cropping system with continuous flooding irrigation and row sowing (8,684 kg ha-1) and the lowest ones were obtained under cropping systems with intermittent irrigation, independently of sowing method. The control cultivars IRGA 417, BRS Jaçanã, BRS Jaburu, and Roraima presented a good performance, under different cropping systems. The test lines BRA 051250, BRA 051126, CNA 10900, BRA 051135, and CNA 110114 are promising for future cultivar releases to the local production systems." |
