早稻早熟新组合农艺性状比较研究

Comparison of Agronomic Characters of New Early Maturity Rice Hybrid Combinations

将8个早稻早熟新组合与对照品种浙733进行比较,分析了各新组合的农艺性状和产量结果。结果表明:W两优3418较对照增产达极显著水平,增幅为6.59%;株两优4204、株两优21和株两优212较对照增产达显著水平,分别增产5.04%、4.85%和4.48%。上述4个新组合丰产性好、早熟、抗逆性强、落色好,可在南昌地区大面积推广。

The agronomic characters and yield of eight new early maturity rice hybrid combinations were analyzed.The results showed that the yield of W liangyou 3418 was very significantly higher than Zhe 733,which increased by 6.59%.The yields of Zhuliangyou 4204,Zhuliangyou 21 and Zhuliangyou 212 were significantly higher than Zhe 733,which increased by 5.04%,4.85% and 4.48%,respectively.The four hybrid combinations had the characteristics of high yield,early mature and strong stress resistance,which should be extended in a large area in Nanchang.
