The study was conducted to analyze the genetic characteristic of young shoot homogenates for coagulation and browning in citrus. Genotypes of some cultivars and Korean landraces used for conventional cross breeding programs were proposed from evaluating segregant ratio of segregant seedlings for coagulation and browning. An evaluation of coagulation was conducted by homogenizing young shoots with phosphate buffer and transferring it immediately on blotting paper and that of browning by homogenizing, centrifuging, and standing it for 1-2 days at room temperature. Mandarins including ‘Wilking’, ‘Fina’, ‘Murcott’, and ‘Dancy’ and a Korean landrace of ‘Sadookam’ were classified into coagulation and a pumelo of ‘Tanigawa’ and Korean landraces of ‘Dangyooza’ and ‘Byungkyool’ into non-coagulation type. Browning type included mandarins or mandarin hybrids of ‘Benibae’, ‘Wilking’, ‘Fina’, ‘Kiyomi’, ‘Dancy’, and ‘OkitsuWase’ satsuma and non-browning included a pumelo of ‘Tanigawa’, a mandarin of ‘Murcott’, and some Korean landraces of ‘Sadookam’, ‘Byungkyool’, and ‘Dangyooza’. The prediction of genotypes for coagulation and browning was possible by evaluating the segregation ratio of some their hybridized seedlings.
