摘要
楠丰9A是温州市农业科学研究院选育的中籼野败型三系不育系。该不育系不育性稳定,花粉败育率99.99%,典败率97.53%;柱头紫色,午前花占67.0%,柱头总外露率71.62%,其中双外露率30.95%;株型适中,分蘖力强,穗大粒多;配合力强,穗数、穗总粒数非加性效应显著,株高、结实率则有一定负面作用;高胶稠度,中低直链淀粉含量,中感稻瘟病和白叶枯病。2009年通过浙江省农作物品种审定委员会技术鉴定。
The indica CMS line Nanfeng 9A was bred by Wenzhou Academy of Agricultural Sciences.The line has stable sterility with abortive rate of 99.99% and 97.53% of abortion during monokaryotic stage;purple stigma,67.0% of blossom rate,71.62% of stigma exposure rate,30.95% of double exposure;moderate plant shape,strong shooting ability,big panicle and quantities of grains;strong combing ability,panicle number and total grain number showed significant non-additive allelic effect but negative effect on plant height and setting rate;high gel consistency,middle-low content of amylase,moderately susceptible to rice blast and bacterial blight.It was approved by Zhejiang Crop Approval Committee in 2009.
