Fundamental studies on rice breeding through hybridization between Japanese and foreign varieties. XI. On the tetrasomic constitution with respect to C-locus of an Indian variety, Surjamkhi.

Abstract

We previously reported on the extraordinary modes of F₂ segregation of anthocyanin coloration in some hybrids between distantly related rice varieties (Kondo and Mizushima, 1964). Other anomalous ways of segregation observed in crosses in which an Indian variety 'Surjamkhi' always took part as a parent are described here. The varieties used in the crosses consisted of nine Japanese and three Indian ones as shown in Table 1.
