摘要
甬优4949是宁波市种子有限公司和武汉佳禾生物科技有限责任公司用"甬粳49A"作母本,"F9249"作父本配组育成的三系籼粳杂交中稻品种。2017—2018年引进建瓯市水源乡作机插、机收再生稻机械化种植。头季稻植株表现生长整齐,株型紧凑,结实率高,丰产性好,中抗稻瘟病;再生季表现良好。总结了甬优4949在建瓯市水源乡作再生稻机械化种植表现及高产栽培技术。
A three-line Indica-Japonica hybrid mid-season rice variety Yongyou 4949 was bred with Yongjing 49A as female parent and F9249 as male parent by Ningbo Seed Co., Ltd. and Wuhan Jiahe Biotechnology Co., Ltd. From 2017 to 2018, machine-transplanted and machine-harvested of ratooning rice was introduced into Shuiyuan Township of Jian,ou City. The first crop of rice showed regular growth, compact plant type, high seed setting rate, good yield and moderate resistance to rice blast. In the regeneration season, the performance was good. The mechanized planting performance and high yielding cultivation techniques of Yongyou 4949 as ratooning rice in Shuiyuan Township of Jian,ou City were summarized.
