水稻新品种镇稻10号的丰产稳产性及其利用

High and Stable Yield of New Rice Variety of Zhendao 10 and Its Utilization

[目的]为水稻生产中合理利用镇稻10号提供依据。[方法]以2004-2005年度江苏省水稻新品种区域试验和生产试验结果为分析资料,采用高稳系数法,结合产量变异系数和适应度,对镇稻10号和对照武运粳7号进行比较。[结果]在2004-005年区域试验、2005-2006年区域试验和生产试验中,镇稻10号的平均产量分别为9 008.258、655.008、319.15 kg/hm2,分别比对照增产3.27%、3.59%、5.37%;高稳系数分别为90.56%、86.33%和70.41%,均大于对照;产量变异系数分别为3.53%、8.33%、26.50%,均小于对照;适应度分别为57.14%、71.43%、75.00%,均大于对照。[结论]镇稻10号是一个高产稳产、丰产性好的晚粳稻新品种,具有较好的广适性,增产潜力大,适宜在沿江和苏南等中高产地种植。

[Objective] The aim was to provide the basis for the rational utilization of Zhendao 10 in the rice production.[Method] With the regional experiments and the production experiment results of new rice variety in Jiangsu Province in 2004-2005 as analyzing data and combined with the yield variation coefficient and the fitness,the Zhendao 10 and the control of Wuyunjing 7 were compared by using high stability coefficient method.[Result] In the 2004-2005 regional experiments,2005-2006 regional experiments and the production experiments,the average yield of Zhendao 10 were 9 008.25,8 655.00 and 8 319.15 kg/hm2,resp.,increasing by 3.27%,3.59% and 5.37% than that of the control.Their high stability coefficients were 90.56%,86.33% and 70.41%,resp.,being all higher than that of the control.Their yield variation coefficients were 3.53%,8.33% and 26.50%,resp.,being all lower than that of the control and their fitness were 57.14%,71.43% and 75.00%,resp.,being all higher than that of the control.[Conclusion] Zhendao 10 was a new late Japonica rice variety with high and stable yield and good fertility,which had better wide adaptability,large increasing production potential and was suitable to plant in the high-middle producing areas.
