Description

A kind of single flower inbred isolation method of capsicum
Technical field
The invention belongs to field of plant variety breeding technology, be specifically related to a kind of single flower inbred isolation method of capsicum.
Background technology
Capsicum is generally first to bloom to split afterwards medicine, and every flower lasts about 3d by opening into to wither.The stamen pollen vitality is the highest with the same day of blooming, and the front 1d of blooming takes second place, and bloom front 2d and the rear 1d of blooming are the most weak, and its active pollen ratio is respectively 85%, 58%, 21.3% and 19%.Gynoecium 2d before blooming is the tool fertility, but the strongest with the same day of blooming, and the front 1d of blooming takes second place.The pollination fruit-setting rate of bloom front 2d, blooming front 1d and the same day of blooming is respectively 21.4%, 57.1%, 71.4%, and the rear 2-3d gynoecium fertility of blooming obviously weakens or loses.After self-pollination, 2-4h pollinia on column cap is sprouted, and the 8-12h pollen tube enters ovary, and the 12-20h pollen tube enters in blastular and discharges sperm through the hole of bead, and the female male cell of 14-30h merges, the nuclear division of 18-40h primary endosperm, the division of 4d left and right zygote.Evidence, after first pollen tube discharges pollen through the hole of bead in blastular, the hole of bead is closed, to stop entering of other pollen tubes.Pollen germination be take 20-26 ℃ as best, fruit-setting rate during with relative moisture 55-75% for the highest.When daily mean temperature, higher than 30 ℃, relative air humidity, lower than 40% or when above higher than 90%, causes harmful effect to result.
In capsicum breed breeding process, the material isozygotied in order to obtain allelomorph, must allow capsicum carry out the selfing column cap of own gynoecium (the same pollen in spending award).But capsicum is a kind of Chang Yihua pollination crop, its natural outcrossing 20%.In order to guarantee selfing, must, in the pedestrian's work isolation of advancing of blooming, prevent cross pollination.According to the characteristic of growing of aforementioned capsicum, isolation time is advisable to the rear 2d of blooming with the front 1d of blooming.The method of capsicum list flower selfing isolation has the bagging method; Tiretube process, twine cotton method (" comparisons of three kinds of autocopulation methods of capsicum " Shen Suxiang etc., " seed " the 3rd phase in 2006); Adhesive plaster twines subsides method (Liu Jinbing etc., 2009) and solution film forming method (Chai Weiguo etc., 201110181629.7) etc.
The bagging method is to select the large bud of blooming tomorrow or the day after tomorrow, and the paper bag of that make with parchment, long and wide all about 3cm entangles, paper bag base portion knuckle, then clamp with clip.The shortcoming of this method, the one, do paper bag time-consuming; The 2nd, during operation, tender petal and anthocaulus easily is bruised and fractures.
Tiretube process is that the plastic suction pipe of appropriate diameter is cut into to 2cm length, and an end slightly pinches sealing after softened by baking with the alcohol lights, during selfing, large petal is entangled and gets final product.The shortcoming of this method is that plastic tube is waterproof, airtight, there is no elasticity, and after the petal quilt cover, petal can't be upheld, and inner moisture is large, and ripening rate is low.
Twining the cotton method is to tear to get a fritter absorbent cotton, and cotton fiber is pulled open, and is wrapped on petal, and bud is snarled.Its shortcoming is higher to twining colored specification requirement, too pine cotton easily fall maybe to hold onto petal, the too tight growth that can affect its later fruit.
It is to use medical proof fabric that the capsicum petal is wrapped that adhesive plaster twines the subsides method.Shortcoming is time-consuming while wrapping up in petal, and efficiency is lower; Petal is also excessively fettered simultaneously.
The solution film forming method is to be the blend solution that 5-10%, sodium carboxymethylcellulose mass concentration are 0.5-2% by deionized water preparation sodium alginate mass concentration, petal is immersed in blend solution, until the junction of calyx and anthocaulus.The shortcoming of this method, the one, obtain solution bothers; The 2nd, petal to be processed is to estimate the large petal of opening after 6-12h, and the time that capsicum blooms mostly is point in the mornings 6-11, therefore needs between the lights or soak the flower processing with solution at night, and operation is inconvenience very.
Summary of the invention
The single flower inbred isolation method that the purpose of this invention is to provide a kind of with low cost, environmentally friendly, capsicum that effect is good.
