Problems solved by technology

[0003] However, Majia pomelo has the characteristics of self-incompatibility, and the self-pollination seed-setting rate is low. Pollen from other pomelo varieties is often used for artificial pollination to increase the fruit-setting rate, but there are many seeds, and the number of seeds per fruit is 80-120 , seriously affecting its commodity and market competitiveness
Some studies have shown that seedless fruits can be obtained through external environmental influences, hormone induction, radiation treatment, etc., but so far, there has not been any report on the successful acquisition of seedless Majia pomelo

Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific examples. The following examples are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0015] The red heart pomelo used as the test material of the present embodiment adopts Majia pomelo, and a method for producing seedless pomelo through pollen radiation mutagenesis of the present invention specifically comprises the following steps:

[0016] (1) Collection of sour pomelo pollen: collect 1000-2000 sour pomelo flowers that are about to open and full, put them in a clean plastic bag and bring them back on the same day, when most of the petal tops of the flowers are cracked by 1-2mm, select the top of the petals Crack the flowers of 1-2mm, cut off the anthers in the flowers with scissors, and place them in a petri dish with weighing paper at the bottom, spread the anthers in each petri dish in a flat layer, cover th...

Abstract

The invention discloses a method for developing seedless pomelos by virtue of radiation induced mutation of pollen. The method comprises the following steps: (1) carrying out collection and radiation treatment on sour pomelo pollen; (2) carrying out castration and pollination on red pomelos; (3) carrying out flower thinning and bagging; and (4) removing bags in good time. According to the method, the sour pomelo pollen is radiated by virtue of <60>Co-gamma ray, and fruits of seedless pomelos are obtained by virtue of manual pollination; the method is applicable to multiple varieties of citruses; the processed red pomelos are seedless, and the quality of the fruits is not remarkably changed after the processing; and the operation steps are simple, the probability for acquiring seedless fruits is high, and furthermore, the excellent quality of the variety can be still remained.

Description

technical field [0001] The invention relates to a method for producing seedless fruit through pollen radiation mutation, in particular to a method for producing seedless pomelo through pollen radiation mutation. Background technique [0002] The Majia pomelo in Guangfeng County, Shangrao City, Jiangxi Province is an excellent local variety selected in the mid-1980s. It is named "Majia pomelo" because it is produced in Majia Natural Village, an ancient village in Danan Town. It is a variety of red heart pomelo , Majia pomelo has excellent characteristics such as large fruit shape, juicy and refreshing, sweet taste, low sugar, pink flesh, storage resistance, and rich in nutrients, and is favored by consumers. [0003] However, Majia pomelo has the characteristics of self-incompatibility, and the self-pollination seed-setting rate is low. Pollen from other pomelo varieties is often used for artificial pollination to increase the fruit-setting rate, but there are many seeds, and...
