Abstract

Six cytoplasmic male-sterile sorghum, Sorghum bicolor (L.) Moench, lines (KS34 through KS39), which have cytoplasms from sources other than the milo group, were tested for fertility expression in F1 hybrids produced with nine lines, and their organelle DNAs were examined by restriction endonuclease fragment analysis. Three of the KS lines had cytoplasms indistinguishable from milo male-sterile cytoplasm; the remaining three lines differed from milo both in fertility response and their mitochondrlal DNA restriction patterns. Chloroplast DNA restriction patterns of all six KS lines were indistinguishable from that characteristic of milo chloroplast DNA. The results indicate a relationship between mitochondrial DNA and genetic behavior of the male-sterile cytoplasms. These cytoplasms may be useful in broadening the cytoplasmic base of hybrid sorghum production.
