In the present system, any cultivar that has more sets of aril
chromosomes than non-aril is classified as an OB+, RB+, or OGB+.
This page presents first-generation seedlings, from crosses between a
member of the
fertile family of halfbreds and a diploid aril. These crosses produce
only OB+, RB+ and OGB+ offspring, depending on whether they have onco
heritage, regelia heritage or both, and are thus relatively easy to evaluate.
