Evaluation of Kenaf Breeding Lines in Heavy Moisture Condition of Paddy Rice Field

In Korea, global warming caused by CO2 and excess production of rice socially have been a big issue. We should take a number of measures to alleviate both matters. Of plants, kenaf(Hibiscus cannabinus L. 2n=36) is an annual herbaceous crop of the Malvaceae family, which is known for its economic importance. Biological yield of kenaf is about 3-4 times that of forest and CO2 assimilation capacity is about 4-5 times that of trees. Also, it contains aerenchyma in adventitious roots that helps kenaf grow in submergence condition such as paddy field. Therefore, this study was conducted to select elite lines with submergence tolerance through outbreeding and mutation.
