Summary
Chromosome doubling has been a limiting factor for production of doubled-haploids, a means of obtaining fruly homozygous individuals, and a time-saving alternative to repeated selfing for the creation of inbred lines. The existence of genetic, environmental and genotype × environment interaction effects on chromosome doubling ability of sugarbeet (Beta vulgaris L.) haploids was investigated. Haploids were derived from four distinct, highly heterozygous diploid populations through in vitro culture of unpollinated ovules. Ovule-derived plants were treated with colchicine to double their chromosome complement. Environmental effects were determined from replication of the experiment at seven dates. Both genetic and environmental factors were found to affect chromosome doubling ability of sugarbeet haploids. No significant interaction between genotype and environment was identified. The presence of genetic effects on chromosome doubling ability is discussed with regard to its implications on breeding programs.
