Apple Pollination - continued

Hidden away in Crane & Lawrence's book "The Genetics of Garden Plants" are some interesting figures which disagree with some of the rules which have grown up around apple pollination.

Here are the numbers of mature fruit which resulted from treating different apple flowers with various pollens. The blossom is listed first; pollen second. T denotes triploid.

Blenheim,T35 flowers 3 fruit (Ribston, T)
Blenheim ,T72 flowers 1 fruit (Crimson Bramley,T)
Crimson Bramley,T51 flowers 1 fruit (Blenheim Orange,T)

CONCLUSION - Very limited data, but it appears that some triploids may pollinate other triploids quite well.


Cox's Orange124 flowers 9 fruit (Ribston,T)
Lane's Prince Albert57 flowers 4 fruit (Crimson Bramley,T)
Cox's Orange160 flowers 12 fruit (Blenheim Orange,T)
Lane's Prince Albert38 flowers 2 fruit (Blenheim Orange,T)
Lane's Prince Albert109 flowers 4 fruit (Blenheim Orange,T)
Peasgood Nonesuch42 flowers 2 fruit (Blenheim Orange,T)

CONCLUSION
Again, limited data, but it seems that triploids can be adequate to good pollinators of certain varieties.


Crane & Lawrence planted the viable seeds. Lack of vigour and feeble growth were observed, especially where both parents were triploids. They concluded that although many triploid varieties are of outstanding merit, the breeder must beware of using them as parents.
