Abstract

The invention discloses a breeding method of late-ripeness red-leaf soft peaches, which uses natural sexual hybridization to breed the new variety of late-ripeness soft peaches. The breeding method of late-ripeness red-leaf soft peaches adopts the bred new variety of late-ripeness red-leaf soft peaches to be naturally hybridized with Anqiu honey peaches, red snow peaches and winter peaches to select high-grade seeds which are stored in sand at the first year; the seeds are sowed in the first third of the March of the spring of the second year, and fruits can be obtained in three years; the high-grade single plants of the late-ripeness red-leaf peaches ripened from September to the end of October are selected, and the peaches ripped around the Shuangjiang solar term are the late-ripeness red-leaf soft peaches. Because the peaches of the invention are bred by natural sexual hybridization according to the late-ripeness heritable principle of Anqiu honey peaches, red snow peaches and winter peaches, the peaches are big and have purple and red color, regular shape, fragrant and sweet mouth feeling, 18 percent to 19 percent of sugar content and soft pulp. After sufficient ripeness, the peel can be taken off, the pulp is white and tender, the juice content is high, and the ripeness is late. The invention solves the problem that no soft peach is supplied in the period, and enriches the fruit market in winter.

Description

The mating system of the soft peach of a kind of late-maturing red autumnal leaves

Technical field:

The present invention relates to carry out the cultivation method of the soft peach of a kind of late-maturing red autumnal leaves of the late-maturing soft peach new varieties that the nature sexual hybridization breeds out.

Background technology:

Peach is widely planted in China North China and areas to the south thereof, is the important species of good fruit output.Also development was very fast in recent years for late peach, but generally was that outward appearance is not attractive in appearance in 9-10 month maturation, and taste is general, does not generally just have bright peach to go on the market after October.And soft peach does not also find to have this kind now.

Summary of the invention:

The invention provides that to carry out the mouthfeel that the nature sexual hybridization breeds fragrant and sweet, pulp is soft, the mating system of the soft peach of a kind of late-maturing red autumnal leaves of ripe late soft peach new varieties.It selects the red autumnal leaves peach new varieties in evening of breeding out for use, adopt with Anqiu honey peach, blood-snow peach, winter peach natural crossing and filter out high quality seed, husky then the Tibetan, 1 year spring, the early March sowing was yielded positive results in 3 years, selected the late-maturing soft peach fine individual plant of the red autumnal leaves of the end in September-10 maturation, connect test through bud grafting, height then, to the observation of yielding positive results, pattern, flower footpath, percentage of fertile fruit have all kept the merit of maternal plant, and this peach ripe before and after the Frost's Descent is the soft peaches of late-maturing red autumnal leaves.Because the present invention utilizes Anqiu honey peach, blood-snow peach, the late-maturing genetic principle of winter peach, carry out the nature sexual hybridization and breed, the big look of fruit is purplish red, the heavy 150-200 gram of general fruit, maximum single fruit weight 250 grams, the fruit type is rectified, mouthfeel is fragrant and sweet, contains sugar up to 18-19%, and pulp is soft, can take pericarp off when fully ripe, the delicate exquisiteness of pulp, fruit juice is many, ripe evening, fill up the blank that does not have soft peach supply this period, enriched the fruit market in winter.

Embodiment:

Mating system of the present invention is: at the beginning of 4 months nineteen nineties, select red autumnal leaves for use, it is male parent that safflower is spent type original seed red autumnal leaves peach again, with the winter peach do maternal sexual hybridization, obtain hybrid seed then, carry out sand November and hide processing, in in late March, 1991 sowing, emerge at the beginning of 4 months, all yielded positive results in 1993, flower is the single flower of pink colour type, wherein the sour plant of the little flavor of fruit is eliminated, and selecting the sweet plant of the big flavor of fruit is red autumnal leaves peach new varieties, works as annual bearing, observe through 2 annual bearings: the maternal plant fruit properties is stable, the characteristic that has kept the male parent red autumnal leaves, fruit is ripe successively from mid-October, is red autumnal leaves peach in evening.In order further to observe the proterties of its maternal plant, adopt scion grafting, bud grafting test and pot experiment, no matter that ground plants is potted plant, shoot growth, leaf morphology, floral organ structure, percentage of fertile fruit and offspring's clone fruit, really look and fruity have all kept the merit of maternal plant.1994 from red autumnal leaves evenings peach with the big individual fruit of Anqiu honey peach, blood-snow peach, winter peach natural crossing, pick out seed, husky then the Tibetan, nineteen ninety-five early March sowing, emerge, last Cheng Miao, yielded positive results in 1997, therefrom select respectively mid-September, mid-October and late October maturation the late-maturing soft peach of red autumnal leaves, as fine individual plant, connect test through bud grafting, height then, until the observation of yielding positive results in 2008, pattern, flower footpath, percentage of fertile fruit have all kept the merit of maternal plant, so ripe this peach is the soft peaches of late-maturing red autumnal leaves before and after the Frost's Descent.

The soft peach of late-maturing red autumnal leaves is the extremely altricial ripe new varieties of cultivating at present.Red blade is the unique distinction of this kind, and pulp soft ripe evening is the precious part of this kind.River village, Xunxian river town, the present Henan Province of the soft peach of late-maturing red autumnal leaves cultivation 8 strains are only arranged, not to external diffusion.

Claims

1, the mating system of the soft peach of a kind of late-maturing red autumnal leaves, it is characterized in that selecting for use the red autumnal leaves peach new varieties in evening of breeding out, adopt with Anqiu honey peach, blood-snow peach, winter peach natural crossing and filter out high quality seed, husky then the Tibetan, early March sowing in 1 year spring, yielded positive results in 3 years, select the late-maturing soft peach fine individual plant of the red autumnal leaves of the end in September-10 maturation, connect test through bud grafting, height then, to the observation of yielding positive results, pattern, flower footpath, percentage of fertile fruit have all kept the merit of maternal plant, and this peach ripe before and after the Frost's Descent is the soft peaches of late-maturing red autumnal leaves.

2, the mating system of the soft peach of a kind of late-maturing red autumnal leaves according to claim 1, it is characterized in that red autumnal leaves peach new varieties in evening are male parent by selecting for use red autumnal leaves, safflower to spend type original seed red autumnal leaves peach again, with the winter peach do female parent and carry out sexual pollen hybridization, obtain hybrid seed then, carry out sand November and hide processing, sowed 1 year spring, emerge, yield positive results, carry out the fine individual plant seed selection, in scion grafting again, bud grafting and two generations of a potted plant grafting and breeding generation, compare test, and fruit, fruit look and the good characteristic of fruity are stable, and fruit is ripe successively during Frost's Descent mid or late October.
