There is no new information about stocks of barley inversions.

Since my report in BGN 18 three new articles have been published on the use of inversions for genetic investigations:

Gecheff, K. I. 1989. Multiple reconstruction of barley karyotype resulting in complete cytological marking of the chromosome complement. Theor. Appl. Genet. 78: 683-688.

Pickering, R. A. 1991. Comparison of crossover frequencies in barley (Hordeum vulgare) and H. vulgare x H. bulbosum hybrids using a paracentric inversion. Genome 34: 666-673.

Säll, T., Flink, J., and Bengtsson, B. O. 1990. Genetic control of recombination in barley. I. Variation in recombination frequency measured with inversion heterozygotes. Hereditas 112: 157-170.
