麥類의 屬間 交雜에 關한 硏究 Ⅲ. Triticum aestivum과 Secale cereale의 屬間交雜 F₁에 있어서 細胞學的 硏究

Studies on the Inter-generic Hybridization in Triticeae Ⅲ. Cytological Studies on the Inter-genetic F₁ Hybrids between Triticum aestivum and Secale cereale

In the present investigation, cytological and genetical research on the F₁hybrid between Triticum aestivum (Chokwang and Jugoku #81) and Secale cereale (Jaelae rye) were carried out. Twenty eight chromosomes were observed in both of the mitotic and meiotic cells of the F₁ hybrid. The chromosomal behaviour of the mitotic cells were considered to be regular but irregular chromosomal orientations were apeared in the meiotic cells. The chromosomes both origin were distributed at random and a high frequency of the chromosome bridges were observed in Anaphase I. Also the micronuclei were observed in 39.5-41.7% of the pollen tetrad.
