영문 초록

This study was investigated to find longevity and fertilizing ability of stored pollens in the Aurantioideae through germination test and artificial crossing. The germination rate of pollen stored for 8 months was 88.3% in Citrus junos, 71.7% in Citrus junos var. Hwanggeumyuza(HG) and 52.0% in Poncirus trifoliata and that of pollen stored for 24 months was 87.7% in C. junos, 12.7% in HG, and 0% in P. trifoliata orange and that of pollen stored for 48 months was 35.0% in C. junos only. Fruit set ratio by pollens stored for 24 months was 50.8% in HG×C. junos, 5.0% in HG×HG and 0% in HG×P. trifoliata, and that by pollens stored for 48 months was 49.3% in HG×C. junos and 0% in HG×HG. The germination rate of seeds set by stored pollens collected that year was 81.7 % in HG×C. junos, 59.7% in HG×HG and 38.9% in HG×P. trifoliata, and those of seeds set by pollens stored for 24 months or 48 months were 63.8% and 66.7%, respectively in HG×C. junos. The phenotype of hybrids of HG×C. junos was mostly intermediate type of their parents.
