芥藍雜種優勢研究初報

Abstract

以11個原始品種自交一代與4個栽培品種為對照品種，評估以此11個品種逢機雜交所獲得的10個雜交組合之株高、莖徑、葉長、葉寬、葉重、株重及葉數的超中優勢與超親優勢，其中以 17×19 雜交組合超親優勢最明顯，株高、莖徑、葉長、葉寬、株重及葉數的超親優勢分別為5.9%、 41.9%、44.1%、50%、150.3%、133.7%及11.1%。 10 Combinations resulted from random mating of 11 chinese kale lines were used for the heterosis studies to compare with parents and 4 cultivars as a check. Plant height, stem diameter, leaf length, leaf width, leaf weight, plant weight and leaf numbers were chosen as parameters to evaluate the heterosis over their mid-parent and /or the best parent.
