Petei and Mocoi: two rice cultivars developed through anther culture in Argentine

Abstract

We developed two rice varieties, Petei and Mocoi, through anther culture. These varieties were released in 1997 for commercial cultivation in Argentina. Petei was developed from a cross involving cultivars Quella and Guayquiraro, which were made avaible to the rice program at the Julio Hirschhorm Experimental Station,FCAF. Selected plants from the F population of this cross were used for anther culture the biotechnology laboratory, FCA, UNNE. Mocoi was developed from crossing two F1s (H342 and H161-28-2-2-1). H342´s parents were Guayquiraro and Nucleoryza, whereas H16r28-2-2-1had Calady 40 and lRll03- 15-10 as parents. Anther culture was performed on the F1s and progenies were multiplied for further evaluation.
