"Mloko" crosses reluctantly with macrophylla, but by good fortune the hybrids are fertile in the first generation. "This is surprising, for both in appearance and in chromosome numbers they are different, "mloko" being a diploid (59:) while "Macro" is a tetraploid." The hybrids have characteristics of both parents: coarse leaves, pale ivory-yellow flowers, and extreme earliness. "This race should certainly be used in further crosses, as they would be likely to give something interesting." The F2's, of which the best is Nova, take after the parents, so that in time one may have from seed a nice little planting of early pale yellow peonies.
