VII. 1. Stock list for the eceriferum mutants VII. Lundqvist, U., Svalof AB, S-268 00 Svalov, Sweden and Wettstein, D. von, Department of Physiology, Carlsberg Laboratory, Gamle Carlsberg Vej 10, DK-2500 Copenhagen Valby, Denmark.
 

The eceriferum (cer) genes control the synthesis and excretion of the epidermal wax coating. To date 1523 induced and 4 spontaneous mutants have been localized by diallelic crosses to 76 loci. All alleles in locus Cer-yy are dominant; the alleles Cer-n⁹⁶⁹, Cer-q¹⁴⁴⁰, Cer-t⁹⁷⁷ are also dominant, while other alleles in the same loci are recessive. The mutants in all other loci are recessive.

The present list is a continuation of the stock lists published in Barley Genetics Newsletter Vol. 1, p. 97, 1971, Vol. 3, p. 110, 1973, Vol. 5, p. 88, 1975, Vol. 7, p. 92, 1977, Vol. 9, p. 135, 1979 and Vol. 12, p. 169, 1982, and comprises 170 new alleles.

The following correction is necessary for stock list IV, Vol. 7, 1977:

p. 94: Locus cer-zj¹²⁴⁷ is cer-ys¹²⁴⁷

The following correction is necessary for stock list VI, Vol. 12, 1982:

p. 169 and p. 172: cer-yr⁴³⁹ is cer-yc⁴³⁹
