通过对优质香稻内优航148亲本特征特性的观测，发现内香2A午前花比例低、开花不集中、花期长、柱头外露率低等因素是造成内优航148制种产量不高的主要原因，总结出一套提高内优航148制种产量的技术措施：定准播差期、培育壮秧、增加母本移栽密度、培育高产苗架、采取辅助措施提高母本异交结实率等。

Based on high quality scented rice optimal navigation within Neiyouhang 148 parental characteristics of observation, and the result showed the cause of low yield for Seed Production of Neiyouhang 148 was low proportion, bloom concentration low, long flowering, stigma exposure rate factor. This paper summarized a set of technical measures to increase the optimal navigation within Neiyouhang 148 seed output include: probable sowing phase difference, cul-tivating seedlings, increased maternal transplanting density, high-yielding seedlings, auxiliary measures are taken to improve female parent in seed setting rate, etc.
