Inheritance of Black-hull and Relationship between Heading Time and Darkness of Phenol-reaction Color of Hull in Remote Crosses of Rice

Inheritance of the phenol-reaction color of hull in some remote crosses of rice was controlled by single dominant gene and there was no segregating distortion by the hybrid sterility. In the cross of Josaengtongil×Minehikari, inheritance of black-hull at ripening stage was controlled by 3 complimentary genes and one of them was a gene controlling the phenol-staining of rice hull. Heading date was inherited by some complimentary or poly genes and lateness was dominance. The genes related to the darkness of phenol-reacted color of rice hull were inherited quantitatively and linked with a part of genes controlling the heading time of rice.
