摘要：

Rye secalins were analyzed in the progeny of three test-crosses by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) using unreduced and reduced extracts of total seed proteins. Segregation for two ω-secalin bands and two 40K γ-secalin bands was studied in the three crosses. Both kinds of proteins showed a very tight linkage (0-25 ±0·25 per cent recombination), finding one recombinant in 394 seeds. Segregation for two high molecular weight (HMW) secalin bands was analyzed in one test-cross. The data indicated linkage (36·03±4·12 per cent recombination) between the structural genes for ω and 40K γ secalins (Sec 1) and for HMW secalins (Sec 3). © 1990 The Genetical Society of Great Britain.
