Description
Technical field
The present invention relates to the crossbreeding of oranges and tangerines, relate in particular to a kind of method that shortens juvenile period of hybrid tangerine.
Background technology
The oranges and tangerines crossbreeding technology can be fundamentally through the mode of genetic recombination, makes the comprehensive parents' of filial generation oranges and tangerines new varieties advantage, have parents' excellent proterties concurrently, but the breeding cycle of conventional hybridization oranges and tangerines is long, and it is very long that its main cause is exactly the virgin phase of oranges and tangerines.The virgin phase of oranges and tangerines is meant that oranges and tangerines are from year time number that planting seed experiences to blooming.Generally, behind the oranges and tangerines planting seed, arrive the 7th year or just began to bloom in the 8th year, promptly the virgin phase of oranges and tangerines is taken 7～8 years, adds that follow-up horticultural characteristics is observed with genetic stability to identify, breeds a hybrid tangerine kind and on average takes consuming time more than 18 years.This characteristic has greatly hindered the raising of oranges and tangerines breeding work efficient, also causes oranges and tangerines to become one of the longest fruit tree of crossbreeding cycle.Therefore, shorten the research of virgin phase of oranges and tangerines and become the key point that improves oranges and tangerines breeding work efficient.
The existing known U.S. that carries out the oranges and tangerines crossbreeding the earliest, though the crossbreeding history in 116 years is arranged, the hybrid tangerine kind that it brings out is very few.Japan has specialized in the culture technique of hybrid tangerine in the period of 1960～1970, make the virgin phase of oranges and tangerines shorten, and also takes 4 years (seeing table 1) but lack most.After this, do not make further progress in the field for the research of shortening the virgin phase of oranges and tangerines.
