Non-green males from a cross between N2 males and abu-14 ok1789)/mIn1 abu-14 ok1789 were crossed back to mIn1 heterozygoteso rebalance the strain.

Yellow-green male flowers hang from threadlike stems; the female flowers, usually in pairs on short, hairy stems on the same tree, develop into prickly burs enclosing three-sided, sweet-flavoured nuts.
