고추 품질 관련 특성 연구를 위한 F6 RIL 집단의 원예적 특성 평가

Evaluation of Horticultural Characteristics in F 6 RIL Populations for Research to Quality-determining Traits in Chilli Pepper

Thirteen horticultural characteristics included fruit color, fruit shape, fruit-tip orientation and others were evaluated using an intra-specific population of 129 F6 recombinant inbred lines (RILs), which derived from a cross between ‘Mandarin’ (Capsicum annuum L.), large sized yellow bell pepper, and ‘Blackcluster’ (Capsicum annuum L.), small sized, deep purple fruit colored and highly pungency. There were 12 patterns of fruit color changed during fruit maturity. The most distribution of the pattern was from green to red observed in 51 RILs, the following pattern was green to purple and ivory to orange in 45 and 8 RILs, respectively. Red mature fruit color was observed in 99 RILs, orange color in 17 RILs, and yellow color in 13 RILs. The fruit shape was divided into three major groups. Triangular fruit distributed highest number of RILs (64 lines), the following was oval shape (52 lines) and cardioid shape (13 lines). Fruit-tip orientation was also examined and resulted that erect type was observed in 79 lines, and pendant type was in 50 lines. The presence of variability of characteristics in study population can be utilized for research of various fruit quality-related traits in the future.
