两系亚种间杂交稻赣亚1号的选育与应用

赣亚1号是江西省滨湖农科所用广亲和籼型光温敏核不育系培矮64S与粳型恢复系Hb-01配组选育而成的两系亚种间杂交稻新组合，是目前国内亲缘关系最远的实用型亚种间组合。2001年12月通过江西省科技厅组织的成果鉴定,2002年2月通过江西省品种审定委员会审定。该组合具有株型理想、产量高、米质较优、抗性强、耐肥抗倒、弱感光、易制种、适应性广等特点，适宜在长江流域作中稻栽培。

Breeding and Application of Two-line Intersubspecific Hybrid Rice Combination Ganya 1

Ganya 1 is a newly developed two line intersubspecific hybrid rice combination derived from Pei'ai 64S, an indica type PTGMS line and Hb 01, a japonica type restorer line. It is the practicable intersubspecific hybrid combination which has, up to now, the widest genetic distance between its two parents in China. In February, 2002, it was examined and approved to release to farmers' fields in Jiangxi Province. The combination shows the characteristics of ideal plant type, high yielding ability, good grain quality, strong resistance to diseases, coldness and lodging,a weak photoperiod sensitivity, easy hybrid seed production and wide adaptability, and it is suitable for planting as medium rice in Yangtze River Valley. The key technical points of its cultivation and hybrid seed production were also introduced briefly in this paper.
