摘　　要：用具有代表性的１８个水、陆稻品种，在云南思茅夏季的低温长日照下旱栽及海南三亚冬季的高温短日照下水栽表明，云南粳型水稻主体亲源对光、温敏感，水栽时植株升高不显著；矮杆籼型水、陆稻品种及粳型陆稻品种的生育期受光、温、水影响不大，但水分使籼稻的植株显著升高。云南籼、粳陆稻在高温、短日水栽时。生育期显著缩短，植株显著降低。对光、温、水均不敏感的矮秆粳型陆稻ＩＲＡＴ２１６等。在两种条件下的生育期和株高变化不大。利用两种条件进行一年两代陆稻新品种选育和亲本评价，可加速世代进程和选育广适性的陆稻品种。varieties of paddy ane upland rice were selected to plant in Simao during thesummer with low temperature, long day length and upland ecological condition, and inSanya during the winter with high temperature、short day length and irrigation condition.The comparison was made of the days for heading and the plant height in the two places.The results indicated that Yunnan japonica core parents was not sensitive to the day lengthand the temperature for its days for heading,and the effect of irrigation on the plant heightwas not significant as well. There is not much difference for semidwarf indica paddy rice,upland rice and japonica upland rice in the days for heading under the upland ecological orirrigation conditions, but the plant height of indica rice was much higher under theirrigation condition, Upland japonica and indica rices from Yunnan but planted in Sanyahad their days for heading shorter and their plant height significantly shorter.too. Nomatter in Simao or in Sanya,IRAT216 was not sensitive to the day length.to thetemperature and to the irrigation condition in its aspects of the days for heading and theplant height.Through the parents evaluation and offspring breeding in the two places andunder the two conditions,not only generation could be promoted, but also breeding forpaddy and upland rices of wide adaption could be achieved.
