Primary Report on the Rlant Character Chang of“Xunza-29”of Dian Type Hybrid Rice in Water and Dry Conditions

根据１９９０～１９９４年滇型杂交粳稻“寻杂２９”水栽和旱种的试验数据和调查资料，从“寻杂２９”在水、旱条件下植株性状变化和产量形成的种种差异，论述该品种对不同生态环境的抗逆性和适应能力，初步探索出杂交水稻“寻杂２９”旱种的生长发育及其栽培特点，供生产应用参考。

This paper presents the experimental data and investigative information ofDian Type hybrid rice growing in water and dry fields from 1989～1994. According tothe differenees of plant characters and the foimation of output of Dian type hybrid riceunder water and drv conditions, the stress resistance and adaptability to differenteeological enviroment of this variety were discussed. The developmental and agronomiccharacters of“Xunza 29”of Dian type hybrid rice growing in dry fieldswas studiedprellminarily.The results of this investigation may used in production.
