Comportamiento de 12 líneas de arroz en la zona de Sancti Spíritus.

The work was carried out at the "Sur del Jíbaro" Grain Research Territorial Station Sancti Spíritus, Cuba, 12 rice lines were evaluated during four years together with three comparison witnesses. Lines 4614, 4675, 10322 and the IACuba-41 and IACuba-42 witnesses remained among the most profitable in each of those years, with values above 7 t / ha and without statistical difference between them, in addition to the three lines have the cycle at maturation of the grain shorter than that of the J-104 control. All lines behaved as resistant and intermediate to the Sogata, as well as resistant to acame and shelling. In order to evaluate the behavior of 12 rice genotypes in Sancti Spíritus and select those with the best behavior, the work was carried out. [ABSTRACT FROM AUTHOR]
