节水抗旱稻恢复系旱恢37号的选育与利用

Breeding and Utilization of Water-saving and Drought-resistant Restorer Line Hanhui 37 in Rice

旱恢37号是上海市农业生物基因中心用节水抗旱稻恢复系旱恢3号为母本、早熟水稻恢复系测49为父本杂交,F1代再与抗稻瘟病高产恢复系成恢448复交,后经多代选育而成的节水抗旱稻恢复系,具有抗旱、抗稻瘟病、恢复力强、花粉量足等特点。旱恢37号与节水抗旱稻沪旱7A配制的组合旱优737于2018年通过云南省品种审定。

Hanhui 37, derived from the three-way cross among Hanhui 3(a water-saving and drought-resistant restorer line), Ce 49(an early-maturing restorer line) and Chenghui 448(a blast-resistant and high-yielding restorer line) followed by selection and identification for drought resistance and blast resistance over years, is a water-saving and drought-resistant restorer line in rice developed by Shanghai Agrobiological Gene Center. It performs well in droughtresistance, blast resistance, restoring ability and pollen load. Its hybrid combination Hanyou 737(Huhan 7 A/Hanhui 37) was registered and released by Yunnan Crop Variety Appraisal Committee in 2018.
