This paper introduced the breeding process, yield performance and characteristics, and the high-yield cultivation technology of new edible sunflower variety AR9-9293. The promotion of edible sunflower varieties and cultivation technology could achieve the effects of improving the level of the sunflower cultivation, promoting the development of rural and agricultural economy and increasing farmers＇ income, as well as positively promoting development of the society and adjusting agricultural industry structure.展开更多

We selected some quality resources from 300 types of domestic and foreign seed,carried out the seed resistance experiment. From comparison of parent strain and filial generation in agronomic traits,ornamental traits,and stress resistance,we obtained special traits of Hemerocallis'jin yan'. Flower diameter of'jin yan' is larger than that of parent strain; seed stalk is higher than parent strain; it inherited evergreen feature of parent strain; the flower color is brighter than parent strain; the flowering stage is about 45 days,and it has reflowering phenomenon; in winter,it keeps evergreen; it is high in stress resistance,and suitable for planting in Yangtze River Delta region. The new Hemerocallis'jin yan'has high afforestation and promotional value in Yangtze River Delta region.展开更多
