Genetic analysis for haploid-regeneration responses of hexaploid-wheat anther cultures.
1995
Moieni A. | Sarrafi A.
Genetic variability in response to anther culture was investigated in 49 winter hexaploid wheats, comprising 33 pure lines (F10) derived from a composite cross programme and their 16 parental genotypes. All genotypes were grown in a randomized block design with three replications in a controlled greenhouse. The number of embryoids and total plant regeneration per 100 anthers, as well as the numbers of green and albino plants regenerated per 100 embryoids, were measured. Significant genetic varability was observed among the 49 genotypes for all the traits studied. All traits showed high heritability. Among the genotypes compared, DC(2)30N and IBPT-40 gave the best results for the production of embryoids and IBPT-78 had the highest value for the production of green plants. The genotype IBPT-34 developed a large number of albino plants, and it should be useful as a parent in studies to determine the genetic control of albino plants in wheat.
