by G. Künzel.

Footnotes to Table 2 are missing in BGN 23:157-163.

2c) Obtained from mutation experiments with seeds of unmarked BTT plants

d) Trisomic plants of unmarked BTT lines crossed as females to 'marked' BTT lines bearing the same msg gene; 'marked' BTTs selected as segregants in F3 or later generations

e) 'Marked' BTT lines crossed and reselected for agronomic improvement

f) LS line harbours in addition to the linked msg and lethal gene the translocationT4-6ae which is closely linked to both genes; 'marked' BTTs selected from the progeny of translocation heterozygotes

3) In all cases lethality at an early seedling stage

4) Based on the total progeny (trisomics and lethal disomics) and summarized for lines having the same translocation, msg and lethal gene
