Abstract:
Taking 6 eggplant materials that had different thermal tolerance traits as parents,according to the Ⅳproject of the Griffing1/2p (p-1) to compound combination,a normality hereditary of thermal tolerance in F2 was tested to judge whether it belongs to quantitative traits in eggplant.The results showed that heat injury index,membrane permeability,free proline content,superoxide dismutase activity performed symmetrical distribution in the combination of ‘CLN2001A’ב01143’.The experiment performed quantitative traits frequency distribution characteristics of multiple gene control.χ2 test showed that four thermal tolerance traits was in accord with normal distribution in this combination,and belonged to a continuous variables.Conformed to quantitative traits,thermal tolerance belonged to quantitative trait in eggplant.It was feasible that application of quantitative genetics method on eggplant for thermal tolerance traits genetic analysis.
