STUDIES ON THE BREEDING BEHAVIORS OF SEVERAL CHARACTERS IN CHESTNUTS, CASTANEA SPP. : I. Inheritance of Orange-kernel Character and the Characteristics of their Seedlings.

Abstract

The kernel color of normal chestnuts is generally observed to be buff or creamy yellow, but a kernel character called orange kernel has appeared in the nuts of several varieties in Japanese chestnut cultivars (Castanea crenata Sieb. et Zucc.). The occurence of this character is expressed phenotypically only when a gene is in homozygous condition. All seedlings derived from orange-kernel chestnuts showed albino character under the day-light condition, but these seedlings under the low light intensity (400 Lx.) developed light-green leaves.
