Breeding technology for triploid hydrid cucumber

Abstract

The breeding technology features that before crossbreeding, one of the parent is doubled into tetraploid; the trploid as female parent and a diploid parent are interplanted under strict separating condition and pollinated naturally; and after harvesting cucumber seeds of male parent and female parent separately triploid hybrid is separated via water selecting process. It this way, the propagation of parent and the crossbreeding are performed simultaneously.

Description

(1) Technical field

[0001] The invention relates to a cucumber breeding method, in particular to cucumber ploidy breeding. (2) Background technology

[0002] The use of hybrid breeding technology makes use of cucumber heterosis. The existing hybrid breeding technology selects different parents with genetic differences, and purifies the parents into inbred lines through methods such as self-crossing purification, and then hybridizes them into single-cross and three-cross varieties. kind. Or it can be used as a top cross with local elite varieties, and the first-generation hybrids can show the yield and disease resistance advantages of super-parents. Diploid hybrid cucumbers have made progress in yield, but they have no advantage in quality. The development of fruit seeds consumes a lot of nutrients, which reduces the nutritional content of edible parts, makes the taste and taste worse, and affects the cucumber in the vegetable market. proportion. There is a breeding method...
