Abstract
Defective plants, ranging in degree from lethal to chlorophyll streaking of the leaves, are shown to be due to a factor or factors in the cytoplasm of the popcorn inbred P2. Five distinct genomes were found to be "incompatible" in P2 cytoplasm although the degree of abnormality varies between genomes, indicating a nuclear-cytoplasmic interaction in this material. One of the most distinctive characteristics of the defective P2 cytoplasm is the extreme phenotypic variability found in F1 hybrids involving P2 females. The substitution of WF9 for P2 chromosomes in P2 cytoplasm is equally as abnormal as the original F1 hybrid.
