Inheritance of Root Epidermal, Xylem and Pholem Colour in IPC-126 × PM Cross of Tropical Carrot (Daucus carota L.)

Dr. Selvakumar R

Carrot (Daucus carota L.) is the most important dietary sources of bioactive compounds, antioxidants and phytochemicals which are essential part of human health. Improvement of multivitamin with multi-nutritional varieties of carrot, there is essential need of inheritance pattern of root epidermal, phloem and xylem colour and it nutritional profile. Considering these objectives in view, we designed experimental platform with two different coloured nutritional carrot inbred lines were taken which are IPC-126 and PM having uniform epidermal, outer and inner core colour of purple and orange-red respectively. The F1 generations of both IPC-126 and PM were conditioned with purple epidermal and xylem colour and orange-red phloem colour. Subsequently F1 progeny were self-pollinated to get F2 generations of IPC-126 and PM. The F2 segregation of both IPC-126 PM, root epidermal and xylem colour was governed by single dominant genet which we denoted for purple as ‘P’ and for orange-red (or). Moreover, orange-red (OR) is dominant over purple in phloem colour (‘p’). These genetic inheritance of root epidermal, phloem and xylem colour and it nutritional profiling would help to accelerate carrot nutritional quality breeding especially anthocyanin and total carotenoids with uniform inner and outer core.
