Research Abstract

New gh lines derived from a cross between ‘Leaf Star’ and‘Takanari’ with a thick culm and high yield were developed. The breaking strength of the basal internode was higher than both parents, because it had the highest section modulus. The results of this study suggested that the culm properties such as super thick culm and thick sclerenchyma contributed to superior lodging resistance in rice cultivars used for feed or biofuel use, maintaining good digestibility or high efficiencyof saccharification.
