Seed number=seed sum/pollination fruit refers to sum, the difference of analysis different disposal combination single fruit Setting percentage.
2 test results
2.1 Different Cross Combinations intermolecular hybrid affinity differences compare
The plant quantity that every combination can collect seed is respectively 9 ~ 22 plants and differs, about 4 to 6 months acquirement seeds after hybridization pollination test,
Then quantity statistics are carried out, such as table 1.Each cross combination can obtain hybrid seed, but the quantity variance for obtaining hybrid seed is aobvious
It writes, single fruit Setting percentage is respectively 5 ~ 1420 there is also significant difference, various combination hybrid seed sum, the average seed of single fruit
Number is respectively 0.009 ~ 1.980.
Wherein, L1 combination is highest with the cross combination cenospecies subnumber and Setting percentage of No. 1 × LW of bronze, and bronze 1
Number seed number is combined with the cross experiment R1 of another male parent material RF and Setting percentage is also higher as female parent, respectively 657
Grain and 0.896 occupies in 8 combinations the 2nd, illustrates under test conditions, makees maternal cross combination compatibility for bronze 1 and is better than
Other combinations show preferable in terms of Setting percentage；And No. 35, No. 30 and No. 32 are poor with the affine sex expression of male parent material,
It may be related from the different female parent material meiosis processes fertility for generating gamete.
(LW hybridizes identical female parent material with RF), and cenospecies subnumber and single fruit Setting percentage exist from different male parents respectively
Difference, overall performance is lower for the cross combination Setting percentage that RF makees male parent, and when being measured to pollen germination power, it has been found that
RF pollen amount and germination rate are lower than LW, therefore from the point of view of improving Setting percentage, and LW ratio RF is preferably to be used as male parent material.
Thus also illustrate, the apolegamy of hybrid strain material influences crossbreeding success or not very big.Bronze 1 is made maternal hybridization
It combines compatibility and is better than other combinations；LW is best male parent material.
The difference of Setting percentage between 1 Different Cross Combinations of table
The different pollination comb positions of 2.2 female flower buds and pollination female flower development stage influence hybridization Setting percentage
Bract is successively unfolded at interval of 1 ~ 2 d after male bud extraction is sagging, this test female parent material uniformly stays 7 combs, each to handle
Different plants pollination comb position has differences because pollination same day bract degree of opening is different, and every single plant pollination comb position and comb number are not
It is identical to the greatest extent.Same plant difference comb position is set seeds, and situation is also different, and the single comb highest seed number of L1 combination is 142, and is singly combed minimum
Seed number is 0；For the seed number that the different fruits of same comb obtain between referring to there is also significant difference, single fruit highest seed number is 27,
And the minimum seed number of single fruit is 0, through quantity statistics such as table 2.
In addition to the head (the 1st comb) of L4 combination and tail (the 7th comb) two combs there is no seed, other comb positions can be planted
Son.It is respectively 12.318 ~ 36.001 that L1, which combines the average seed number that different pollination combs position is singly combed, the average seed number difference of single fruit
It is 0.712 ~ 2.081；L2 combination is single, and to comb average seed number be 0.168 ~ 2.806, and the single fruit seed number that be averaged is 0.010 ~ 0.167；
L3 combination is single, and to comb average seed number be 0.200 ~ 5.160, and the single fruit seed number that be averaged is 0.012 ~ 0.309.According to the 1st comb to the 7th
The sequence of comb, single to comb downward trend after Setting percentage and the overall performance of single fruit Setting percentage first rise out, i.e., intermediate 3rd comb, the 4th comb
It is higher to hybridize Setting percentage, and the comb of head two (the 1st comb, the 2nd comb) and the comb of tail two (the 5th comb, the 6th comb) Setting percentage are lower.Illustrate difference
Pollination comb position and fruit refer to intermolecular hybrid Setting percentage, and there are significant differences.Pass through the knot of the 1st comb to pollination maternal plant fruit ear to the 7th comb
Seed effect is compared analysis, the 3rd comb of centre, the 4th comb hybridization Setting percentage highest
The difference of the different pollination comb interdigit Setting percentages of table 2
From table 3 it can be seen that each cross combination of the 1st stage obtains a certain number of hybrid seeds, i.e., when female flower bud petal piece is
It will open or just open, just have been provided with Enumerable infinite set when column cap is also in closed state；Bract spreading angle increases later, column
The solid effect of head pollination also rises with it, and the 2nd stage respectively combined single fruit Setting percentage index and increases than the 1st stage；When the 3rd stage
Bract spreading angle is greater than after 80 °, and hybridization pollination Setting percentage declines than the 2nd stage, so relatively managing to guarantee that column cap is in
That thinks awards the phase, and hybridization pollination is preferably carried out 10 ° to 80 ° of bract spreading angle of the 2nd stage.Pass through bract difference the first transaction of a day's business angle
The comparative studies of degree hybridization Setting percentage, when 2 stage that 10 ° to 80 ° of bract spreading angle, carries out hybridization pollination single fruit Setting percentage
Highest.
The difference of the different female flower development stage pollination hybridization Setting percentages of table 3
2.3 different pollinated stages influence hybridization Setting percentage
There are certain influence in different hybridization pollination periods on the acquisition of banana hybrid seed, this test is respectively in January to December to mother
This material carries out test of pollination, the situation performance difference of setting seeds of Different Cross Combinations.The hybridization examination that September, October are carried out
It tests and was divided into for the 5th phase, Guangxi Zhuang Autonomous Region In Nanning Area is late summer, weather at the beginning of the autumn at this time, illumination, moderate temperature, and environment is dry
It feels well penetrating, strain rate is set seeds in remaining each combination and single fruit seed number was significantly lower than for the 5th phase, and see Table 4 for details.Therefore, climatic environment item
The relatively comfortable September of part, October carry out hybridization pollination test, and it is more preferable to hybridize situation of setting seeds.Meanwhile the germination test in later period
It was found that in the seed of the convenient September of environmental condition and hybridization acquisition in October, seed has embryo rate also relatively high, equally also says
Bright, environmental factor has an impact to cross compatibility.Hybridization pollination period more has in the relatively comfortable September of climatic environment condition, October
Conducive to pollen germination and fertilization.
