摘　　要：通过田间和室内试验相结合的方法,初步研究了水稻新品系‘沪选101’的主要农艺性状。结果表明:‘沪选101’的多数农艺性状与‘秀水128’和‘秀水134’差异显著;该品系生长势强,株高101.86 cm,茎坚韧有弹性,生育期全株绿色,分蘖力强,剑叶及倒二叶叶长和叶面积无明显差异,叶宽均显著小于对照;产量构成因素与对照差异不明显,产量10 839.15 kg/hm^2,比‘秀水134’增产16.13%。田间观察显示,‘沪选101’具有较强的抗倒伏能力,稻瘟病、纹枯病发病较轻,稻曲病发生较少。The main agronomic characters of a new rice strain ‘Huxuan 101’ were preliminarily studied by field experiment and laboratory experiment.The results showed that most agronomic characters of ‘Huxuan 101’were significant different with ‘Xiushui 128’ and ‘Xiushui 134’.‘Huxuan 101’ grew strongly with tough and elastic stem,the plant height was up to 101.86 cm and the plant remained green during the whole growth period;It had strong tillering ability,its flag leaf and second leaf showed no obvious differences with ’Xiushui 128 ’and’Xiushui 134’ in leaf length and leaf area,but their width were significantly less than ‘Xiushui 128’ and‘Xiushui 134’;The characters of ear length,grains per spike,spike and grain weight also showed no significant difference among the three varieties（line）;The yield of ‘Huxuan 101 ’was up to 10 839.15 kg/hm^2,which increased 16.13%than ‘Xiushui 134’.Field observations showed that ‘Huxuan 101 ’had a strong lodging resistance and mildly suffered from rice blast and sheath blight disease,rice false smut occurred less.
