摘要

Nb11 was the elite waxy maize inbred line, which was bred by 60 Co-γ irradiation combined with conventional breeding techniques. Nbl 1 had good characteristics of high quality, prematurity, high combining ability, disease resistance, lodge resistance and extensive adaptability. Two waxy com hybrid varieties named ' keyubai 202′ and ′ kebainuo 8 hao' were bred by utilizing Nb11 as the lather. Several new waxy com varieties combined by Nbl 1 directly or indirectly had good performance in different area test.%糯玉米自交系Nb11是利用60Co-γ辐照诱变技术与常规育种技术相结合选育出的优良自交系.该自交系具有优质、早熟、高配合力、抗逆性好、适应性广等特点.目前,已直接利用该自交系选育出科玉白202和科白糯8号2个优质、高产糯玉米新品种.此外,用Nb11及其转育系组配的糯玉米新组合在各级试验中表现优良.
