Abstract
Crossing ability was examined in the F1 hybrids of B. campestris .times. B. oleracea, and the character and somatic chromosomes of F2, B1 and the hybrid plants were investigated. Different types of normal gametes might be produced in the F1 hybrids with 19, 38 and 28 chromosomes. In the F1 hybrids with 19 chromosomes, most normal egg cells had 19 chromosomes, which were unreduced gametes, and normal pollen grains had 10 chromosomes. In the spontaneous F1 amphidiploids with 38 chromosomes, normal egg cells had 19 chromosomes and normal pollen grains had 10 and 19 chromosomes. In the F1 hybrids with 28 chromosomes, normal egg cells had 10, 19 and 28 chromosomes and normal pollen grains had 10 chromosomes. New type plants of B. napus were obtained from the progenies of 3 types of the F1 hybrids.This publication has 1 reference indexed in Scilit:
