Germinable F1 seed was obtained from the cross O. sativa subsp. japonica (2n = 24) x O. minuta (2n=48). The majority of F1 plants did not survive the plumule stage; only three adult F1 plants were raised. The F1 hybrids resembled O. minuta more closely in some characters than O. sativa; in other characters the plants resembled O. sativa or were intermediate between the two parents. The F1 hybrids were highly sterile and extremely susceptible to bunt.
