早熟、高产、优质黄花新品种“金针早”的选育

摘要

金针早是从地方品种“渠县黄花”天然杂交后代系统选育而成的早熟、高产、优质黄花新品种.在区域试验中平均鲜花产量20856.3kg/hm2,较对照增产10.93％；在生产试验中平均鲜花产量20706kg/hm2,较对照增产10.42％,始花期较对照平均提早15d.抗叶锈病和叶斑病,抗风、抗旱、耐寒、耐湿能力较强.%The new H.citrina variety -Jinzhenzao was selected and bred from the natural hybrid progenies of Quxian variety which was cultivated locally. The average flower yields of Jinzhenzao were 20856.3kg/hm2 in regional tests and 20706kg/hm2 in productive tests in Sichuan province, 10.93% and 10.42% respectively higher than those of the CK-Quxian. The early flowering season was averagely 15 days earlier than that of the CK. This new variety had good resistance properties to leaf rust, leaf spot, wind, drought, coldness and moisture.
