Novel variety cultivation method for inducing petal mutation of physalis alkekengi l

Abstract

The invention belongs to the technical field of plant propagation, in particular to a novel variety cultivation method for inducing petal mutation of physalis alkekengi l. According to the novel variety cultivation method for inducing petal mutation of physalis alkekengi l, the cultivation method comprises the following steps: sterile petals are obtained through flower bud development and cultivation, pale green embryogenic calli are obtained by inducing embryogenic calli from the flower petals, the embryonic calli are induced by ethyl methanesulfonate to differentiate into embryoids with differences, the embryoids grow into individual plants and the like, so that a novel physalis alkekengi l cultivated variety with characteristics of strong independence, high purity of genetic informationand clear source and the like of the individual plants is obtained. The novel physalis alkekengi l cultivated variety is genetically stable, and can be utilized for strain cultivation and construction of physalis alkekengi l mutant library.

Description

technical field [0001] The invention belongs to the technical field of new plant varieties, and in particular relates to a method for cultivating new varieties by inducing mutations in Physalis petals. Background technique [0002] Physalis (Physalis alkekengi L.) is a perennial erect herbaceous perennial plant of the Solanaceae Physalis genus. Ghost lamps, etc., are eaten with fruits. Fruiting pedicels about 2-3cm long, mostly covered with persistent pilose; calyx ovoid, 2.5-4cm long, 2-3.5cm in diameter, thin leathery, prominent network veins, with 10 longitudinal ribs, orange or fiery red, covered with Persisting pilose, closed at the top, sunken at the base; berry spherical, orange-red, 10-15mm in diameter, soft and juicy. The flowering period is from May to September, and the fruiting period is from June to October. Physalis is highly adaptable, cold-resistant, heat-resistant, likes cool and humid climates, likes sunshine, and does not choose soil, especially Physali...

Problems solved by technology

[0004] In order to solve the above-mentioned Physalis fruit small, sour, low quality, poor disease resistance, little edible value and low yield, and Physalis common pests such as aphids, cabbage caterpillars, cotton bollworms, etc., resulting in its development and utilization are greatly affected Problems such as limitation, the present invention provides a kind of new variety breeding method of inducing Physalis petal mutation
