Heterosis in brussels sprouts, especially with reference to cold resistance

Summary

Experiments on heterosis in Brussels sprouts are described. The plants obtained after inbreeding showed reduced vigour and gave sprouts of poor quality. The heterosis cross yielded sprouts of a better quality than the original varieties. After the severe winter 1953–1954, it was observed that a heterosis effect for cold resistance also exists. These results are discussed and interpreted according to Jones' dominance hypothesis.

Samenvatting

Proefnemingen over heterosis bij spruitkool zijn beschreven. De door inteelt verkregen planten hadden minder groeikracht en leverden spruiten van slechte kwaliteit. De heterosis-kruising gaf spruiten van betere kwaliteit dan de oorspronkelijke rassen.

Na de strenge winter 1953–'54 kon worden vastgesteld, dat een heterosis-effect voor kouderesistentie bestaat. Deze resultaten worden besproken en verklaard met behulp van de dominantiekoppelingstheorie van Jones.
