[0044] Cross breeding between Lagerstroemia fauriei and Lagerstroemia (indica xfauriei) 'Tuscarora'

[0045] (1) Crossbreeding with Lagerstroemia fowlerii (♀)×Lagerstroemia chinensis (♂);

[0046] Insect pest control: From June 15th to 30th, 2012, during the budding stage of Lagerstroemia fowleri, the flowering branches of Lagerstroemia flockliar were sprayed with drugs to prevent insects from laying eggs in the buds, and 20kg of water was sprayed with 50ml of methamidophos , 2 times a week, a total of 4 sprays;

[0047] (2) Flower thinning: On July 5, 2012, keep the strongest 3-4 branches of each flower branch of Lagerstroemia flockii, remove two side buds from each branch, keep the largest flower bud in the middle, and finally keep the second flower bud on each flower branch. 10 flower buds that bloom every day, and then spray 1000ppm NAA on the entire flower branch to prevent new branches from sprouting at the incision and form secondary flowering;

[0048] (3) Bagging, e...

Abstract

The invention discloses a crossbreeding method for lagerstroemia fauriei Koehne, and particularly relates to a crossbreeding method for lagerstroemia fauriei Koehne and lagerstroemia (indica x fauriei) 'Tuscarora'. The method comprises the following steps: (1) pest control; (2) flower thinning; (3) bagging, emasculation and pollination; (4) aseptic seedling obtaining; (5) transplantation. By adopting the crossbreeding method for seed selection, the advantages of the lagerstroemia fauriei Koehne and the lagerstroemia (indica x fauriei) 'Tuscarora'; are combined, the stem is brownish red and brown, the panicle is large and beautiful, the flower is red in color, the ripening rate is high, the obtained seeds are full, the filial generation blooms early, and the application prospect is wide.
