Breeding of Two-line Intersubspecific Hybrid Rice “278S/Zhong L208”

两系亚种间杂交一季稻278S/中L208组合是籼型光温敏核不育系278S与粳稻广亲和恢复系中L208配制而成的。介绍了278S和中L208的选育经过及其特征特性。此外,还介绍了278S/中L208组合的高产栽培及其制种的技术。

The single -season rice ＂278S/Zhong L208＂ was two -line intersubspeeific hybrid rice, which was the combination of the photo -thermo -sensitive genic male sterile line 278S and the wide compatibility Japonica restorer line ＂Zhong L208＂. The breed- ing process and traits of 278S and Zhnng L208 were introduced. The technique of high - yielding cultivation and seed production of ＂278S/Zhong L208＂ combination was also summarized in this paper.
