Heritability and correlation structure of nectar and floral morphology traits in Nicotiana alata.

Abstract excerpt

The heritability and genetic basis of nectar traits have been rarely studied in the field, where plants are exposed to environmental factors that could mask underlying genetic effects. Heritabilities and variance components were estimated for nectar and morphological traits of Nicotiana alata, using a partial diallel design. The main experiment was conducted in a Missouri experimental garden using a randomized...
