【摘要】 长日第二光周期对不育系育性转变的诱导效应,决定于其本身短日第一光周期感光性强弱。据此,可将目前已发现或转育的光(温)敏感核不育水稻划分为3种类型,即光敏感型核不育水稻、温度敏感型核不育水稻和光温互作型核不育水稻。用起源予低纬度地区或具有短日第一光周期强感光性的晚籼作为转育材料,是选育籼型光敏感核不育水稻的可能途径。更多还原

【Abstract】 The induction effects of photoperiod or thermoperiod-sensitive ge-nic sterile lines depend On their background thermo-photoperiodic response.Inaccordance with their photoperiodic responses they can be grouped into threetypes.1/photoperiod-sensitive genie male sterile rice;2/thermoperiod-sensitiverice; 3/photoperiod-thermoperiod sensitive rice.It is also discussed that,if trans-selecting late indica rice originated in low latitude regions or that with strongphotosensitivity,it is a possible path for obtaining photoperiod-sensitive ind-ica genic male sterile lines.更多还原
