Measurements of natural selection on floral traits in wild radish (Raphanus raphanistrum). II. Selection through lifetime male and total fitness

摘要: It has often been suggested that selection on floral traits in hermaphroditic plants should occur primarily through differences male fitness. However, measurements of lifetime fitness have lacking. We measured a variety wild radish using measures derived from genetic paternity analysis. These estimates were then combined with female the same to produce based total Contrary prediction above, there was no strong evidence for morphology any three years study, but increased flower size one year. The main determinant both and all number; this lead moderately positive correlations between years.
