Abstract: | In infection experiments with clover rot (Sclerotinia trifoliorum
Erikss.) on 9 pairs of diploid and corresponding autotetraploid families arisen from chimaera plants the tetraploid families proved to be more resistant than their corresponding diploid families. Significant interaction between family pairs and ploidy level was demonstrated and this is an indication that there may be differences between different genotypes with respect to the effect of autotetraploidy on resistance to clover rot in red clover.
Samenvatting Bij kunstmatige infectie met klaverkanker van 9 paren (uit chimaere planten van rode klaver afkomstige) diploide en daarmede corresponderende autotetraploide families bleken de tetraploide families grotere resistentie te vertonen dan de daarmede corresponderende diploide families.Uit een vergelijking van de families bleek dat er verschillen in invloed van de autotetraploidie op de resistentie tegen klaverkanker zijn. |
