Book Description

Excerpt from Sterility Relationships in Maine Apple Varieties It is well known by horticulturists that most apple varieties are self-sterile and that for good Sets of fruit provision must be made for pollen varieties and for the transmission of pollen from tree to tree. A knowledge of what varieties are inter-fertile is necessary in selecting those to be planted together or for top working certain trees in large blocks of self-sterile varieties. Most investigators have concluded that honey bees are essential for carrying pollen from one variety to another. A list of self-sterile and self - fertile apple varieties and those known to be inter-fertile has been published in bulletin 287 of the Maine Agricultural Experiment Station. In this bulletin are included sterility relationships of varieties grown in all parts of the country, but. Complete records are not available for some of the most important varieties grown in Maine. In some cases the. Conclusions were tentative, as they were based on insufficient numbers. It is also evident from recent work that local condi tions peculiar to New England may make unnecessary certain recommendations which may be applicable to other regions.
