Inheritance of Root Epidermal, Phloem and Xylem in White Pale × PM Cross in Tropical Carrot (Daucus carota L.)

Dr. Selva Kumar R

Carrot (Daucus carota L.) is the most important biennial winter root vegetable crop cultivated throughout the world. It has been classified as vitaminized food due to its rich sources of β-carotene, lycopene, lutein and anthocyanin in orange, red, yellow and black colour of carrot. Recent increasing awareness of nutritional security, there is urgent need to improve multivitamin with multicolored and multinutritional tropical carrots. For this achievement, there is need to clear understanding of genetic nature and inheritance pattern of root epidermis, phloem and xylem colour of carrots. Therefore, considering these objectives our experimental platform were designed and evaluated by hybridization between White Pale ×PM and PM ×White Pale crosses followed by self-fertilization of F1 for advancing generation of F2 generations. In these experimental studies, both F1 progeny of White Pale ×PM and PM ×White Pale were expressed orange-red colour epidermal and xylem colour with yellow colour of outer-core. The F2 progeny of White Pale ×PM and PM ×White Pale crosses were clearly segregated into ratio of 3: 1 of Mendalian model with colour grouping of Royal Horticultural Colour mini chart with larger populations. It confirmed that root epidermal and xylem colour is conditioned by single dominant gene which notified as ‘OR’ (orange) and ‘y’ (yellow) and further it more, yellow colour (Y) is dominant over orange colour (or) of phloem.
