摘要：
The contorted hazelnut, Corylus avellana L. f. contorta (Bean) Rehder, is an ornamental tree prized for its twisted trunk and branches. Crosses of normal growth habit cultivars and 'Contorta', as it is commonly called, produced all normal growth habit seedlings. Sib matings of these normal seedlings of 'Contorta' produced offspring in the ratio of 3 normal:1 contorted, while backcrosses to 'Contorta' segregated 1 normal:1 contorted. These segregation ratios indicate control of contorted growth by a single recessive gene for which we propose the name twisted and the symbol Mi. Progenies segregating simultaneously for growth habit and leaf anthocyanin indicated that the two loci are independent.
