A cytological and physiological study of haploid diploid polyembryony in flax linum usitatissimum l



A cytological and physiological study of haploid diploid polyembryony in flax linum usitatissimum l



Agronomie 7(8): 567-574



The origin of haploid-diploid twins in flax (Linum usitatissimum L.) genotypes 'Rocket 4' and 'RA91' was found to be the division of the egg cell to give two independent egg cells, one which is fertilized and the other of which develops parthenogenetically into a haploid embryo. The twinning frequency increased with high temperatures during plant growth and flowering and with age of the macrogametophyte at fertilization.
