영문 초록

Forty lines of gerbera (Gerbera hybrida) were developed by self-pollination of 80 commercial pot varieties. The lines show wide variation in both qualitative characters (flower and disk color) and quantitative characters (flower diameter, peduncle length and days to flowering). The inbred lines showed varying degrees of inbreeding depression in peduncle length and flower diameter as much as 66-88% and 89%, respectively. As selfed generations were advanced, the quantitative characters of lines became uniform as measured by variance among 30 individual plants per generation. It is postulated that a few number of genes are controlling flower color since most lines of third or fourth selfed generation showed uniform color. Hybrids between developed lines of third selfed gereration showed considerable level of heterosis in flower diameter, peduncle length, and number of flowers, and considerably lower degree of heterosis in days to flower.
