Narrative
Diploid (2n=2x-16) bred for biotechnology research and development. Developed by 3 cycles of half-sib family recurrent phenotypic selection for improved regeneration of plants from tissue culture from PI 251830. Has 100% embryogenic genotypes and more than 50% of these will produce well-formed, vigorous plantlets after 50 days on regeneration medium. Agronomically important traits nearly identical to PI 251830.
