| 摘 要： | 本研究选用20个早籼品种(系)分期播期研究了产量与品质的相关。结果如下:早籼正季栽培时产量与糙米厚度和容重显著相关,与精米垩白指数和直链淀粉含量呈一定程度的相关,与其他品质性状相关不密切。大多数早籼品种(系)作连作晚稻栽培时产量下降,品质提高,而早籼品种8004作连作晚稻栽培时品质提高,产量并不下降,表现高产。

| Abstract: | The study on the correlation between grain yield and grain quality characters was conducted by means of the devided sowing times for 20 early indica rice varieties(strains) planted in Changsha. The results were as follows: The significant correlativities were showed between grain yield and thickness and weight unit volume of brown rice, the some correlativities were showed between grain yield and chalkness index and anylose content of milled rice, the close correlativities were not showed between grain yield and other grain quality characters when the earlyindica rice varieties (strains) were planted as the double early season rice. Grain yield descended and grain quality raised when a great number of early indica rice varieties (strains) were planted as the double late season rice; but the grain yield of 8004 (a early indica rice variety) did not descended, the grain quality of 8004 raised and grain yield of 8004 was high when 8004 was planled as double late season rice. |
