Screening test on ratoon rice variety in Youjiang valley
摘要
Abstract
[Objective]The purpose nf this experiment was to screen out elite ratoon rice varieties suitable for the production mode "early rice+ ratoon rice+ autumn tomato" in Youjiang Valley, with good thermostabtlity at germination stage,strong regeneration capacity and high yielding to meet needs of local farmers. [Method]Six rice varieties were tested in field to compare the agronomic traits and yield. [Result]Except Xinfengyou 008 and Y-Liangyou ] , the yields of early rice + ration rice of other four rice varieties were higher than the CK, among which the yields of Zhongzheyou 1 , Zhun-liangyou 1141 and Y-Liangyou 5S67 were 13889.6,13836.7 and 13382.1 kg/ha wifh significant increase of 9.60, 9A9 and 5.60%, respectively, while the yield of Shentiartgyou 5814 was t2849.6 kg/ha with only 1.40% increment. The yields of Y-Liangyou 1 and Xinfengyou 008 were 11474.2 and 9979.2 kg/ha and showed significant decrease of 9.46% and 21.25%, respectively. [Conclusion]Zhongzheyou 1 and Zhunliangyou 1141 displayed the best comprehensive performance, Inllowed by Y-Liangyou 5867 and Shenliangyou 5814, the former could be used as main early-seeding ratoon rice varieties, the latter could be used as mid- and late-seeding ratoon rice vareties under production mode "early riee+ rationing rice+ autumn tomato".关键词
