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。
The representative hydroponics of 18 watery and Upland rice cultivars under low temperature and long sunshine in Simao, Yunnan Province, and high temperature and short day in winter in Sanya, Hainan Province indicated that the main source of japonica rice in Yunnan was sensitive to light, temperature and water The plant height was not significantly increased at planting time. The growth period of indica rice, upland rice and japonica rice was not affected by light, temperature and water, but water increased the indica rice. Yunnan indica, japonica rice in the high-temperature, short-term hydroponics. Growth period was significantly shortened, plants significantly reduced. Dwarf japonica rice IRAT216 which is insensitive to light, temperature and water. Growth and plant height did not change much in both conditions. Using two conditions to breed and parental rice varieties in one year and two generations, it can speed up the generation process and breed the widely adaptable Upland rice varieties.
