THE BREEDING OF SIX XINJIANG DWARF WALNUT CULTIVARS

The purpose of this program is to take advantage of the second bearing in early ripening walnuts to select high quality dwarf individual cultivars from a seedling population.
Seeds from the second bearing of nationally graded walnut cultivars ‘Zha343’ and ‘Xinzaofeng’ were sown.
From these, “the relatively low height, early branching, short internodes” types were selected as experimental materials.
They were then transplanted into orchards and evaluated further.
Six dwarf elite cultivars were selected from this work, which included evaluations in comparison to the high quality types ‘Wen 185’ and ‘Xinxin 2’ to determine the best dwarf cultivars.
As a result of this work during the past decade and more, six dwarf walnut cultivars, ‘Xinwen 609’, ‘Xinwen 724’, ‘Xinwen 908’, ‘Xinwen 915’, ‘Xin 916’ and ‘Xinwen 917’ were selected.
Results also demonstrate that development of newly-bred dwarf walnut cultivars from the second bearing seedling population is not only feasible, but also efficient.
