Abstract:
Seeds of early-, middle- and late-flowering breeding lines of common stock, Matthiola incana (L.) R. Br. cultivated under field conditions, were evaluated for their fatty acid compositions. Seeds of early-flowering breeding lines accumulated less linolenic acid (C18:3) and more oleic acid (C18:1) than those of late-flowering breeding lines harvested at the same time. Yield parameters, such as number of seeds per pod and number of pods per plant were lower in early-flowering breeding lines than in the late-flowering ones.However, under a controlled-temperature regime, the fatty acid compositions of all breeding lines were affected by temperature in the same manner: higher linolenic acid levels and lower oleic acid levels were observed in seeds which developed at lower temperatures (12-17 °C). © 1992 Taylor & Francis Group, LLC.
