摘要:
闽葵3号系福建省农业科学院作物研究所利用观赏向日葵品种CS(花瓣白色)为母本,与选育的高世代自交系M1R3-1(花瓣黄色)为父本,经杂交选育出的无花粉观赏型向日葵新品种。该品种经RAPD、ISSR分子标记鉴定证明其为真实杂交后代。经多年多点试验结果表明,闽葵3号观赏性状稳定,花瓣柠檬黄色,颜色鲜艳,无花粉,具分枝性,可作切花生产和庭院观赏种植;生育期92～112d,株高96.0～170.0cm;花盘直径6.4～7.2cm,花朵直径13.7～14.8cm,花瓣数34～39枚,切花瓶插寿命9～14d;生长势强、适应性广、生长期短、可周年栽培,切花产量9.0万～12.0万枝.hm-2。于2011年3月通过福建省农作物品种审定委员会认定,同时总结了其配套栽培技术要点。
Abstract:
Minkui 3 is a new,pollen-free ornamental sunflower variety developed by cross-breeding the CS(with white petals)as female parent and the high-generation inbred line,M1R3-1(with yellow petals),as male parent by the Crop Institute,Fujian Academy of Agricultural Sciences.The new variety was confirmed to be a true hybrid offsping by molecular marker analysis,such as RAPD and ISSR.The results obtained from the cultivation at various sites for several years showed that Minkui 3 could be used for ornamental cut flower production and garden cultivation because of its stable ornamental characteristics,yellow petals,bright colors,pollen-free property and branching capability.Minkui 3 had a growth period of 92-112 days.Its plant height was 96.0-170.0 cm with faceplate diameter of 6.4-7.2 cm,flower diameter of 13.7-14.8 cm,petal number of 34-39,and a cut flower lifespan of 9-14 d.This vigorous,adaptable,new variety had a short growth period,was suitable for year-round cultivation,and provided a cutting output of 90000-120000 piecesm-2.Minkui 3 had passed the provincial appraisal in 2011.The instruction manual for cultivation is also available.
