糯玉米育种研究概况

Waxy Maize Breeding Research Survey

糯玉米以鲜食或青穗加工为目的,在制定育种目标时应综合考虑产量、品质、熟期及抗逆性等因素;在选育自交系时,依据基础材料和育种手段的不同,有6种选育方法:直接选育法、轮回选择法、杂交选育法、群体改良法、二环系选育法和利用现代生物技术选系法;筛选新组合时,应注重果穗外观商品性和口感品质的选择;把现代生物技术和常规育种手段结合起来,加快糯玉米育种的速度。

The waxy corn is used for fresh-cooking or processing.On its breeding mapping out,quantity,quality,maturity and stress resistance should be debated comprehensively.On its breeding inbred lines,there are six kinds of methods according to its basic materials and breeding techniques:selecting inbred lines from naturally pollinated varieties,selecting inbred lines from elite hybrids,selecting inbred lines by means of crossing,selecting second cycle line modifying and modern biotechnology-line selecting.On screening and selecting the new combination,its appearance of the commercial-quality and tasty should be paid attention to.On its breeding speed,modern biotechnology and conventional methods should be combined to accelerate the pace of its breeding.
