Abstract
The invention belongs to Chinese cabbage heterosis utilization field.The present invention adopts self incompatible line stone to transport a self incompatible line hybridization of farming improved crossing kind together special No. one.The crossbreed that the present invention breeds has advantages such as high yield, quality is good, disease-resistant, storability is good.
Description
The invention belongs to Chinese cabbage heterosis utilization field.
The main path of Chinese cabbage heterosis utilization is self incompatible line and male sterile line both at home and abroad at present.Japan begins to use self incompatible line preparing hybrid kind from the fifties initial stage, the domestic Qingdao City institute of agricultural sciences at first adopts cross method to breed " blue or green assorted early rich " in nineteen sixty-eight, and after this self incompatible line becomes the heterotic main path of domestic Chinese cabbage gradually.In recent years, units such as the Shenyang institute of agricultural sciences utilize seed selection Chinese cabbage nuclear gene to make male sterile line mutually, and it is remarkable successfully to make hybrid vigour, the hybrid Chinese cabbage of neat and consistent.More than research is though improved the output of Chinese cabbage unit are to a certain extent.But do not solve the problem of Chinese cabbage quality, disease-resistant and storability difference yet at present.
The objective of the invention is to propose a kind of Chinese cabbage stone that utilizes and do the parent special No. one,, make high yield, quality is good, disease-resistant, storability is good crossbreed with a Chinese cabbage parent hybridization of fortune farming.
Below be described in detail main contents of the present invention:
The present invention adopts the special self incompatible line of stone to make parent's (code name: 77-17-11-12-9-3), transport self incompatible line of farming (code name: 80-38-2-2-3) hybridization improved crossing kind together.
At present by a large amount of tests, bred self incompatible line of new two packet header Chinese cabbage: Shi Te (code name: 77-17-11-12-9-3) * self incompatible line (code name: 80-38-2-2-3) of fortune farming
(1) breeding and feature of two parents of the present invention:
1, self incompatible line of Shi Te (code name: 77-17-11-12-9-3): when late fall, Chinese cabbage grew up to, the individual plant of selecting 50 strains to have this kind feature from the special kind of stone is done kind of a strain, field planting in early spring next year is in the greenhouse, florescence is carried out the individual plant artificial autocopulation, check the ripening rate of each strain during seed maturity, select the low individual plant sowing of index of affinity (its index of affinity of seed=1 of knot in 1 pod) autumn, kind of a strain continues to select and remain when Chinese cabbage grows up to from the good strain system of economic characters, and superseded bad strain is, carried out for 4 generations so continuously, from a large amount of strains are, select.The mixed pollination index of affinity is between 0.2-0.5 in check system.High about 25 centimetres of its leaf-head of the self incompatible line of breeding, the ball top blade is folded to be embraced, the siphonal lobe blade edge, outer leaf white, quality is first-class, because the continuous multi-generation selfing bag heart is looser.Than viral diseases and downy mildew.
(2) breeding and feature of fortune farming No. a self incompatible line (code name 80-38-2-2-3):
When late fall, Chinese cabbage grew up to, the individual plant of selecting 32 strains to have this kind feature from transport kind of farming is done kind of a strain, field planting was carried out artificial individual plant selfing when spring next year, bolting was bloomed in the greenhouse, check the ripening rate of each strain during seed maturity, eliminate the high individual plant of index of affinity, select the low individual plant sowing of index of affinity autumn, kind of the strain that from the good strain system of economic characters, continues to select and remain when Chinese cabbage grows up to, and superseded bad strain is, carry out the three generations so continuously, from a large amount of strains are, select.Through test, be that interior mixed pollination index of affinity is between 0.2-0.7.High about 27 centimetres of its leaf-head of the self incompatible line of breeding with this method, blade is folded to be embraced, the siphonal lobe blade edge, the lobus cardiacus milky, because three generations's selfing continuously, a little less than the growth potential, the bag heart is looser, downy mildew resistance.
(2) breeding and feature of the new two packet header hybrid Chinese cabbages of the present invention:
New two packet header Chinese cabbage are the first generation cross-fertilize seeds that form with special self incompatible line 77-17-12-9-3 of stone and a self incompatible line 80-38-2-2-3 of fortune farming mating.This half-blood leaf-head is high 30 centimetres, the head hypertrophy, and the ball top blade is folded to be embraced, and a leaf covers completely, and siphonal lobe is green, the lobus cardiacus milky, bag heart consolidation, the heavy 3-4 kilogram of individual plant clean vegetables, 7000 kilograms of general per mu yield net weight, quality is first-class, goes into to store anti-storage after the results.Sow and need grow up in 90 days the beginning of autumn in the area, Taiyuan, every mu is stayed the 2000-2200 strain.Viral diseases and downy mildew.
The present invention compares than prior art has following typical advantages:
(1) growth potential is strong, and impoverishment tolerant is suitable for China's most of area plantation.
(2) clean vegetables rate height.The clean vegetables rate of kind is up to 85%-90%.
(3) disease-resistant performance is good.
(4) output height.Than common variety, the present invention can improve output more than 50%.
Below be that example is narrated implementation process of the present invention with new two packet header Chinese cabbage:
New two packet header Chinese cabbage are the first generation cross-fertilize seeds that form with special self incompatible line 77-17-12-9-3 of stone and a self incompatible line 80-38-2-2-3 of fortune farming mating.These two self incompatible lines are that this is bred.Chinese cabbage belongs to the natural cross pollination vegetables.The ether original area is an example, before the Spring Festival the parent is sowed in the ground of growing seedlings at interval in 1: 1 ratio, seedling length moves into the land for growing field crops when arriving 7-8 sheet leaf, the honeybee pollination for the treatment of to leave flowering stage, behind the seed maturity, the seed of gathering in the crops from two parents promptly is the generation seed of process hybridization.
