SUMMARYRandom inbred lines produced by doubled haploidy and single seed descent have been used to estimate the number of genes or more correctly effective factors (k) controlling quantitative characters in barley. Estimates of k obtained by various biometrical methods are generally an underestimate since the effective factor may be considered a unit only in a temporary sense. In the past, estimates of k have been used to predict the range of inbreds extractable from a cross. Alternative and efficient methods are now available to predict the number of inbreds expected to exceed any given standard. Under these circumstances the need to estimate the number of genes is questionable.

Barley Genotypes

Low seed set, owing to partial incompatibility, can limit sexual gene transfer and haploid production efficiency in wide crosses. The inheritance of partial incompatibility in barley Hordeum vulgare L. × H. bulbosum L. crosses and its effect on gamete sampling in doubled haploid production were studied by doubled haploid progeny analysis. The dominant, monogenic control of partial incompatibility in 'Vada' was confirmed. Partial incompatibility in 'Harrington' is also monogenic but appears to be controlled by a different gene. An association between the Inc gene and a deficiency in a stigma–stylodium specific high pI protein was found in the co-segregation analysis of doubled haploid progeny. Segregation analysis of Mendelian markers in doubled haploid progeny showed that there is no evidence that the compatibility status of the parents has an effect on gamete sampling by the bulbosum technique.Key words: barley, haploids, Hordeum bulbosum, incompatibility.
