CN104542253A - Breeding method for disease-resistant summer squashes - Google Patents

Abstract

The invention discloses a breeding method for disease-resistant summer squashes, and relates to the technical field of crossbreeding. Conventional homemade dark-green summer squashes HS96-152 used as a female parent and high-disease-resistance summer squashes GS99-113 used as a male parent are hybridized to obtain a first-filial generation; the first-filial generation is subjected to 6-8 generation separation, purification and rejuvenation to breed summer squashes with strips which extend first and then grow stronger. According to the summer squashes, the post-stage summer squashes cannot be shortened and are green and outstanding in disease resistance.

Description

A kind of selection of disease-resistant custard squash

Technical field

The present invention relates to crossbreeding technology field, be specifically related to a kind of selection of disease-resistant custard squash.

Background technology

The main pumpkin variety of existing market is general, and just to there is sugar-preserved gourd partially short, later stage melon bleaches, the most important thing is in southern open country planting process, anti-virus ability is poor, can only gather about 7-10 melon and pickled cucumbers many, serious even total crop failure, plant substantially cannot setting again, causes very large loss to grower.

Summary of the invention

The object of this invention is to provide a kind of selection of disease-resistant custard squash, the custard squash of its seed selection, can ensure that later stage melon does not shorten, color is green simultaneously, and disease resistance is given prominence to.

In order to solve the problem existing for background technology, the present invention adopts following steps:

1, first choosing maternal is HS96-152 pumpkin variety, and its color bottle green, has rib, and sugar-preserved gourd is long, but disease resistance is slightly poor, fruit colour is too dark, and male parent is GS99-113 pumpkin variety, its high antiviral, colors green, sugar-preserved gourd moderate length, but later stage melon lighter;

2, make female parent by HS96-152 to hybridize as male parent with GS99-113, obtain first-filial generation HDS13-09, by logical for first-filial generation HDS13-09 too much, multiple spot carries out plantation separation 8 generation, therefrom select and meet sugar-preserved gourd requirement and first extend again long thick, color is more maternal more shallow, and disease resistance gives prominence to custard squash HP001;

3, HP001 is carried out the multiple shape of purification of three generations again, finally will keep that proterties is stable not to be separated, by making great efforts finally to select HP14-006 custard squash, this Variety Disease-resistance poison ability is strong, sugar-preserved gourd straight smooth, color is green, later stage melon non-whitening, highly stable inbred line;

4, HP14-006 is hybridized as male parent as maternal with French custard squash parent FB256, first-filial generation HD1123(tentatively titled), show as growth potential strong, individual plant knot melon ability is good, on the ground such as Yunnan, Sichuan, multispots trial shows, anti-virus ability is good, and individual plant can adopt more than 20, melon, and sugar-preserved gourd first extends long thick again, ensure that later stage melon can not shorten, sugar-preserved gourd colors green, later stage color does not bleach, and deeply likes by market.

The present invention has following advantage: later stage melon does not shorten, and color is green simultaneously, and disease resistance is given prominence to.

Embodiment

A selection for disease-resistant custard squash, it adopts following steps:

1, first choosing maternal is HS96-152 pumpkin variety, and its color bottle green, has rib, and sugar-preserved gourd is long, but disease resistance is slightly poor, fruit colour is too dark, and male parent is GS99-113 pumpkin variety, its high antiviral, colors green, sugar-preserved gourd moderate length, but later stage melon lighter;

2, make female parent by HS96-152 to hybridize as male parent with GS99-113, obtain first-filial generation HDS13-09, by logical for first-filial generation HDS13-09 too much, multiple spot carries out plantation separation 8 generation, therefrom select and meet sugar-preserved gourd requirement and first extend again long thick, color is more maternal more shallow, and disease resistance gives prominence to custard squash HP001;

3, HP001 is carried out the multiple shape of purification of three generations again, finally will keep that proterties is stable not to be separated, by making great efforts finally to select HP14-006 custard squash, this Variety Disease-resistance poison ability is strong, sugar-preserved gourd straight smooth, color is green, later stage melon non-whitening, highly stable inbred line;

4, HP14-006 is hybridized as male parent as maternal with French custard squash parent FB256, first-filial generation HD1123(tentatively titled), show as growth potential strong, individual plant knot melon ability is good, on the ground such as Yunnan, Sichuan, multispots trial shows, anti-virus ability is good, and individual plant can adopt more than 20, melon, and sugar-preserved gourd first extends long thick again, ensure that later stage melon can not shorten, sugar-preserved gourd colors green, later stage color does not bleach, and deeply likes by market.
