Crossing of tetraploid L. esculentum (Pearson) by L. peruvianum (P.I. 129149) produced 16 plants. Each plant had 36 chromosomes. At the time of extraction of the seed from the ripe fruit the endosperm was not firm and all embryos were extracted and grown on sterile nutrient agar. The mature plants were extremely vigorous and exceedingly sterile under field conditions at Riverside. Repeated selfing produced no fruit. Crossing with diploid and tetraploid L. esculentum pollen produced no fruit. Nine seedless fruit were set with triploid L. esculentum pollen. One plant showing Curly Top symptoms produced 36 fruit from open pollination. These fruit contained 17 "normal" seeds with firm endosperm. Five plants germinated. 17 fruit were obtained from two other plants. These 17 fruit contained 22 "normal" seeds. Eight seeds germinated. Chromosome counts of these plants have not been made.
