Verbatim
e1“Quantitative genetic parameters associated with the inheritance of biomass yield and related traits were evaluated in Gynandropsis gynandra for selecting appropriate breeding methods for cultivar development”
e2“A total of 331 F1 hybrids generated from a North Carolina mating design II and their 39 parental lines were evaluated in the field and greenhouse”
e3“Overall, hybrids performed better than their parents for stem diameter (21.1%), plant height (34.4%), primary branch length (37.6%), leaf traits (17.5–50.9%), total (80.6%) and edible (54.7%) fresh biomass”

- Intervention effect F1 hybrids of Gynandropsis gynandra had stem diameter 21.1% higher than their parents.
- Intervention effect F1 hybrids of Gynandropsis gynandra had primary branch length 37.6% higher than their parents.
- Intervention effect F1 hybrids of Gynandropsis gynandra had leaf traits 17.5–50.9% higher than their parents.
- Intervention effect F1 hybrids of Gynandropsis gynandra had total fresh biomass 80.6% higher than their parents.
- Intervention effect F1 hybrids of Gynandropsis gynandra had edible fresh biomass 54.7% higher than their parents.
- Association Plant height, stem diameter, leaf traits and plant biomass were positively associated in Gynandropsis gynandra parents and hybrids.
- Association The association of harvest index and time to 50% flowering with biomass per plant and leaf traits changed significantly from parents to hybrids.
- Association The association between harvest index and dry matter content changed from parents to hybrids in Gynandropsis gynandra.
- Observation General and specific combining ability effects were significant in Gynandropsis gynandra.
- Observation Both additive and nonadditive gene action controlled biomass and related traits in Gynandropsis gynandra, with predominance of additive gene action.
- Observation The environment significantly interacted with genotype, GCA and SCA in Gynandropsis gynandra.
- Observation Mid- and best-parent heterosis in Gynandropsis gynandra varied between −51.7% and 192.1%.
- Observation Only positive heterosis was observed for leaf area and total fresh biomass in Gynandropsis gynandra, with average mid-parent heterosis greater than 50%.
- Recommendation Reciprocal recurrent selection is a sound breeding strategy for Gynandropsis gynandra hybrid cultivar development.
- Observation Parents with good GCA and crosses with high SCA and heterosis were identified in Gynandropsis gynandra.
