Plant height is one of the important agronomic traits of rice.Overhigh plant easily led to lodge and reduce output. 摘要株高是水稻品種的重要農藝性狀之一，植株過(guò)高容易引起倒伏而減產(chǎn)。
The genetic covariance between genetic effect components of quality traits and agronomy traits was not significant but that between quality and other plant traits was complicated. 雖然控制品質(zhì)性狀的主要遺傳效應分量與農藝性狀相應遺傳效應分量遺傳協(xié)方差不顯著(zhù)，但在其他相應遺傳效應分量方面存在著(zhù)復雜的關(guān)系。
