甘蔗新品种闽糖93-730的选育研究

Study on Breeding of New Sugarcane Variety Mintang 93-730

闽糖93—730是福建省农科院甘蔗研究所以川57—416为母本、CP57-614为父本，通过杂交选育出的一个优良甘蔗新品种，该品种具有高产高糖、早熟、宿根性强、抗逆性强、适应性广等优良特性。多年多点试验结果表明，闽糖93—730每公顷蔗茎产量94．972t，11～2月份平均蔗糖分15．39％，每公顷含糖量14．594t，比对照种增产1．48％、蔗糖分提高0．36个百分点、增糖4．40％。

Mintang 93 -730 selected from the crossing between Chuan 57 -416 and CP57 -614, is a new sugarcane variety with early maturity, high cane yield, high sucrose content, strong rooting ability, strong tolerance and wide adaptability. The results of planting tests conducted at different sites for several years showed that its mean cane yield was 94.972 t/hm^2, sucrose content in the cane was 15.39% from November to February, and sugar yield was 14. 594 t/hm^2, being 1.48%, 0.36 percent and 4.40% higher than those of the check variety, respectively.
