摘　　要：研究了经辐射诱变育成的糯稻不育系、保持系、恢复系和杂交糯稻的主要生物学特性,分析了杂交糯稻的稻米品质。结果表明,糯稻具有与原品种相同的生育期,相似的农艺性状、穗部和花器性状。糯不育系具有与原不育系相同的花粉不育特性。杂交糯稻保留了原杂交稻的产量水平和产量潜力,此外杂交糯稻具有与常规糯稻鄂荆糯6号相似的稻米品质。The main biological characters of the waxy male sterile lines, maintainer lines, restorer lines and waxy hybrids which had been developed by radiation-induced mutation were studied, and the grain quality of the waxy hybrids were analyzed as well. Sesults indicated that the mutant waxy rice had the same growth duration, similar agronomic characters, panicle and spikelet traits as parent. The waxy male-sterile line had the same pollen sterility characteristic as its parent male-sterile line. The waxy hybrid rice retained the yield potential as original hybrid rice, and the grain quality of the waxy hybrids was similar to the conventional waxy rice Ejinnuo 6.
