甬优6号是浙江省宁波市农科院和宁波市种子公司合作选育的籼粳超高产优质稻新组合,2007年1月通过福建省农作物品种审定委员会审定。漳州市于2006年引进试种,表现出超高产潜力。本文对甬优6号的产量构成因素进行分析,探讨各因素间的内在联系和对产量贡献的大小。结果表明:甬优6号全生育期127-131 d,有效穗8.2-11.6万穗.hm-2,每穗总粒数310-377粒,结实率84%-87%,千粒重24.3-24.8 g;实割产量平均为8.59 t.hm-2,比博优253增产23.6%。本文还总结了甬优6号的高产高效栽培技术措施。

Analysis on the yield structure and cultural techniques of the high quality and high yield combination Yongyou 6

Yongyou 6 is a high yield and high quality hybrid rice developed by Academy of Agricultural Sciences of Ningbo City of Zhejiang Province and Ningbo City Seed Company.It was approved and released by Fujian Crop Variety Approval Committee in 2007.In this paper,in order to explore the fit cultural techniques,the yield and yield components characteristics of Yongyou 6 and Boyou 253(CK) were studied.The result showed that the growth duration of Yongyou 6 was 127-131 days,effective panicles were about 0.82-1.16 million per ha.,mean grains per panicle were 310-377,seed setting rate was above 84%-87%,and 1000-grain weight was 24.3-24.8 g.Compared with Boyou 253,Yongyou 6 had a significant increase in the average yield(8.59 t·hm-2),rose by 23.6%.Moreover,the high-yielding and high-resulting cultural techniques were promoted.
