The rice quality was significantly improved especially for brown rice rate, milled rice rate, head rice rate, chalky grain rate and chalkiness.
施用硅肥能显著改善稻米品质，主要表现为稻米的糙米率、精米率和整精米率显著提高，稻米的垩白粒率和垩白度显著降低。
Variation coefficients of grain chalkiness, translucency and chalkiness were high, but those of brown rice rate, milled rice rate and head rice rate were low.
糙米率、精米率、粒长和长宽比的变异系数较小，垩白米率、透明度和垩白度的变异系数较大。
Correlation analysis showed that the milled rice rate and head rice rate were significantly and positively correlated with silicon rate for the two varieties.
相关分析表明，两品种的精米率和整精米率与有效硅施用量呈正相关。
Results showed that the characters with high heritability are amylose content, seed shape, seed longness, chalkiness rate, brown rice rate and milled rice rate.
结果表明：广义遗传力较高的性状有直链淀粉含量、粒形、粒长、垩白米率、糙米率和精米率。
The major quality problems are higher chalky rice rate, higher chalkiness score, lower head milled rice yield, and poor eating quality.
