Abstract

The invention discloses a seedling breeding method for new high-sweetness blueberry variety. The method comprises the steps of with a blueberry variety Berkeley as a male parent and a blueberry variety Black Pearl as a female parent, respectively carrying out tissue culture on stem tissue of Black Pearl and leaf bud tissue of Berkeley, and promoting differentiation inducing to obtain plants; cultivating plants with good growth conditions for later root cutting; and cutting the plants on a culture medium, thus obtaining the new high-sweetness blueberry variety after 3.5-6.5 months. The culture medium consists of the following components in parts by mass: 28 parts of perlite, 32 parts of live moss, 14 parts of turfy soil, 5 parts of tomato juice, 5 parts of mashed banana, and 70-80% of water. According to the new high-sweetness blueberry variety (M10) cultivated by the method, the fresh blueberry has 15-18% of sugar content, and is much higher than normal blueberry with 10% of sugar content; and the method is specifically suitable for picking for eating fresh blueberry and for brewing blueberry wine.

Description

A kind of seedling-cultivating method of blueberry new varieties of high sugariness

Technical field

The present invention relates to blueberry planting technology, relate in particular to a kind of seedling-cultivating method of blueberry new varieties of high sugariness.

Background technology

Blueberry (Blueberry), means the meaning of blue berry.Be a low shrub, short pin is wild, and particle is little, but the content of anthocyan is very high; The second is artificial culture blueberry, can grow to 240cm high, and fruit is larger, and moisture is more, and anthocyanidin content is relatively on the low side.The Vaccinium plant that the whole world distributes can reach more than 400 to be planted, originate in and main product in U.S.'s U.S.'s blueberry that is otherwise known as.China mainly produces in Daxing'an Mountainrange and forest zone, the Xiaoxinanlin Mountains especially Central Greater Khingan Mountains, and is all pure wild.Just successfully carried out in recent years domestication's cultivation, but taste meta-acid, sugariness is not high, and fruit is less.Eat raw and wine brewing aspect there is certain deficiency.

Summary of the invention

For solving the deficiencies in the prior art, the present invention aims to provide a kind of seedling-cultivating method of blueberry new varieties of high sugariness.

The technical solution used in the present invention is:

A seedling-cultivating method for the blueberry new varieties of high sugariness (being called for short M10), comprises the following steps:

1. the selection of male parent, female parent: select blueberry kind Berkeley as male parent, blueberry kind black pearl is as female parent;

2. group training: get respectively the stem section tissue of black pearl, the leaf bud tissue of Berkeley is organized cultivation, by induction formation plant again;

3. screening: select the good plant of upgrowth situation to cultivate and wait for cuttage;

4. cuttage: on medium, plant is carried out to cuttage, obtain the blueberry new varieties of high sugariness after 3.5-6.5 month.

Medium component in described step 4 comprises according to mass fraction meter:

28 parts of perlites; 32 parts of liver mosses alive; 14 parts of careless beaches soil, 5 portions of tomato juices, 5 parts of banana puree, adding water, to be adjusted to water content be 70%-80%.

Described Berkeley, black pearl kind are blueberry kind known to ordinary skill in the art, that can buy on the market.

The invention has the beneficial effects as follows: the blueberry new varieties of the high sugariness obtaining according to the method for the invention (being called for short M10), eat fruit sugar content 15-18% raw.10% the sugar content far above common blueberry; Especially be applicable to eating raw harvesting purposes and brew blueberry wine.

Embodiment

A seedling-cultivating method for the blueberry new varieties of high sugariness (being called for short M10), selects blueberry kind Berkeley as male parent, and blueberry kind black pearl is as female parent; Get respectively the stem section tissue of black pearl, the leaf bud tissue of Berkeley is organized cultivation, by induction again, forms plant; Select the good plant of upgrowth situation to cultivate and wait for cuttage; On medium, plant is carried out to cuttage, after 3.5-6.5 month, obtain the blueberry new varieties of high sugariness.Described medium component comprises according to mass fraction meter: 28 parts of perlites; 32 parts of liver mosses alive; 14 parts of careless beaches soil, 5 portions of tomato juices, 5 parts of banana puree, adding water, to be adjusted to water content be 70%-80%.Described Berkeley, black pearl kind are blueberry kind known to ordinary skill in the art, that can buy on the market.
