Study on the Inheritance of Fruit Color in Wax Guard
[Objective] To provide references for genetics and breeding of wax guard.[Method] The inheritance of fruit color of wax guard was studied by using two inbred line,P1 and P2,and its F1,F2,BC1,BC2.P1 was a dark green fruit inbred line,P2 was a yellow green fruit inbred line.[Result] All the fruit were dark green in two F1 generations.However,in their F2 generations,segregation of dark green and yellow green color appeared in a ratio of almost 3 to 1.For their backcrosses,all the BC1 showed dark green color when F1 backcrossed to dark green inbred.Meanwhile all BC2 appeared in a ratio of almost 1 to 1 when F1 backcrossed to yellow green inbred.[Conclusion] Fruit color was controlled by one pair of nuclear genes.
