摘　　要：本文概述了特早熟快速灌浆晚粳稻“明珠１号”的植株形态和籽粒特性，生育特点和适宜应用范围，光温反应和根系发育等。研究揭示其光、温反应介于典型早粳和晚粳之间但偏于晚粳；栽培上应强调分蘖肥、促花肥和保花肥的结合，而粒肥的效果较差；施肥量以每６６６．７ｍ２施１９．５ｋｇ尿素为佳；植株的形态特征特性较好，抗倒性、抗病虫害能力较强；米质优，增产潜力大；可作单季晚稻、连作晚稻、机插、抛秧及连晚直播等多种形式栽培应用于生产，也可作特异材料应用于育种。The major morphologcal and grain characters, special growing feature and suitable planting area, reaction to light and temperature (RLT), root development of extra early-ripening and fast grain-filling japonica “Bright-Pearl 1” rice were studied. The results showed the RLT is between those of non-photosensitive japonica and photosensitive japonica but is biased to that of photosensitive japonica. Tillering and flowering fertilizers should be combined to apply. The morphological characters of Bright-Pearl 1 is quite good and it resists to lodging, rice blast, and moderately resists to bacterial blight and brown plant hopper. It also has high yield potential with excellent grain quality. It can be directly planted in the farm field and be used as a speacial parent in rice breeding.
