Abstract

More than 90 percent of domestic consumption of the lettuce occupied leaf lettuce, and the farmer preferred high yield, late bolting and stable expression of anthocyanins. So, this research focused on making resistant to disease, late bolting, and good expression of anthocyanin for lettuce. Based on these characteristic's parents, 11 crosses were created. So we advanced the generation and investigated each generation from F1 to F7. In this year, we selected 90 combination 221 lines which was F2 42 combination 137 lines, F3 4 combination 17 lines, F4 11 combination 27 lines, F5 7 combination 30 lines, F6 1 combination 2 lines, F7 3 combination 8 lines. Among the selected 17 lines, 5007, 5014, 6004, 6005, 6021, 6023, 7001, 7002, 7006, 7007, 7010, 7011, 7015, 7018, 7019, and 7021 which were late bolting and good expression of anthocyanins were investigated their yield. Finally, we selected 5 lines 7001, 7002, 7011, 7018 and 7022 in this year.

본 연구는 내병 만추대이고 적색 발현이 양호한 양친을 중심으로 11개 교배조합을 작성하였다. 선발된 계통은 F2 42조합 137계통, F3 4조합 17계통, F4 11조합 27계통, F5 7조합 30계통, F6 1조합 2계통, F7 3조합 8계통 등 90조합 221계통을 선발하였다. 선발한 계통 중 만추대이면서 색택이 좋은 파종번호 5007, 5014, 6004, 6005, 6021, 6023, 7001, 7002, 7006, 7007, 7010, 7011, 7015, 7018, 7019, 7021 등 17계통은 생산력검정을 하였다. 이중에서 유망한 7001, 7002, 7011, 7018, 7022 등 5개 계통을 선발하였다.
