From 2007 to 2008 , We had taken Zheng Rice 18,Zheng Rice 19,Xin Rice 18,Zhongzhongyou Rice 2005,Yuan Rice 108,Yu-japonica 6(CK)as experimental material made arranged experiments in 6 areas such as Zhengzhou, Yuanyang, Xinxiang, Jiaozuo, Luoyang, Nanyang, Xinyang, Huangchuan in Henan province.We adopted randomized block arrangement to do this experiment,and arranged 3 replications for each variety. The conditions such as the soil types,the soil fertilization,the seed quantity,the seed raising method and the period of bedding out were all different in each area.But all of the varieties were managed with the best planting method in the local area.we made an analysis which studies the growing seasons and the characteristic of output of Japonica.The results are as follows:,1.The influence of the whole growth of Japonica rice varieties in different ecological zones. Whole growth period between the years, Between pilot, Location×year, Variety×year, location×variety×year were all significant difference between Interaction. the order of the whole growth period between the length of locations was: Jiaozuo>Zhengzhou>Yuanyang>Luoyang> Xinxiang>Nanyang>Xinyang>Huangchuan,The range was 22d;the order of Whole growth period between the two species the length: Variety 5> Variety 1, Variety 4> Variety 2> CK>Variety 3, The range was 22d.2. The influence of the height of Japonica rice varieties in different ecological zones. Interactions of Height in the year, the pilot, the variety×year, Location×variety×year all reached significant or highly significant level. Height between the high and low places in the order: Jiaozuo>Nanyang>Zhengzhou>Xinxiang>Luoyang >Xinyang>Huangchuan>Yuanyang, The range was 16.1cm; Height level between the two species in the order:Varieties5>Varieties4>Varieties1>CK>Varieties3>Varieties2, The range was 39.2cm.3. The influence of Japonica rice varieties yield and yield component traits in different ecological zones. Mizuho Long-place order: Jiaozuo > Nanyang > Zhengzhou > Xinxiang >Luoyang>Xinyang>Huangchuan>Yuanyang, The range was 16.1cm; The number of acres of panicles in the order: Luoyang>Yuanyang>Zhengzhou>Huangchuan>Xinyang>Jiaozuo>Xinxiang>Nanyang,The range was 54000 Sui / mu; Into a spike rate of the number of the following order:Luoyang>Xinxiang>Jiaozuo>Zhengzhou>Nanyang>Yuanyang>Huangchuan>Xinyang, The range was 18.6%; Single-panicle number in the order:Jiaozuo>Zhengzhou>Xinxiang > Yuanyang > Luoyang,Huangchuan > Nanyang > Xinyang, The range was 51; Seed-setting rate descending order as follows: Luoyang>Xinxiang>Jiaozuo>Zhengzhou>Nanyang>Yuanyang>Huangchuan>Xinyang, The range was 19.0%; Grain weight in the order:Luoyang > Xinxiang > Jiaozuo > Zhengzhou > Nanyang > Yuanyang > Huangchuan >Xinyang, The range was 2.2; Production of high and low in the order:Jiaozuo>Yuanyang>Zhengzhou > Nanyang > Xinxiang > Huangchuan > Luoyang > Xinyang, The range was 1664.3kg/hm2;Height between the two species in the order:varieties4> varieties3>varieties2>CK, varieties1>varieties5, The range was 7.8cm; Acres of panicles in the order: CK> varieties3> varieties1,5>varieties2>varieties4, The range was 33000Sui/mu;Panicle rate the following order:varieties4> varieties3>varieties2>CK, varieties1>varieties5, The range was 7.8cm; Single-panicle following order: varieties 4>varieties1>varieties2>varieties5>CK, The range was 42.3cm; Seed-setting rate the following order: varieties5>varieties1>CK> varieties3>varieties2>varieties4, The range was 9.0cm; Grain weight in the order: varieties5>varieties2>varieties1> varieties3>CK>varieties4, The range was 2.7g; Yields the following order: varieties1>varieties5>varieties2>varieties4>CK> varieties3, The range was 832.2kg/hm~2.4. Comprehensive Evaluation:We can see a comprehensive analysis of 6 pairs of japonica rice varieties, species 1 in Henan province than those in CK within the eight-point increase, high yield, stability and adaptability are the best performing; Followed by the species 5, 6 yield two cuts.Between variety of 1,5 and CK reached very significant difference level. Rice milling quality is a better variety 5.Comprehensive results of this study, the six varieties Japonica rice in the comprehensive evaluation of eight sites,The yield of Xin Rice 18 (species 1) and yield component traits are better than Yu Japonica 6 (CK) and other species,Demonstrated high and stable yield, wide adaptation and so on.
