两个云瑞系列甘蔗新品系在云南陇川水田旱地的丰产性及稳产性分析
Analysis of the High and Stable Yields of Two New Yunrui Sugarcane Varieties in Longchuan,Yunnan
摘要
Abstract
To better understand the high and stable yield and adaptability of Yunrui 14658 and Yunrui 14599,two new sugar-cane strains in paddy fields and dry lands of Longchuan,Yunnan,and provide the basis for their demonstration and application in production,six-point identification trials of two new strains and one ratoon were conducted in the dry lands and paddy fields of three towns in Longchuan.The results revealed that in both paddy fields and dry lands,Yunrui 14658 presented significantly greater average cane yields and sugar yields than did the double controls.The high stability coefficients for both average cane yield and sugar yield exceeded those of the double controls,and the coefficient of variation of sugar yield was lower than that of the double controls.The coefficient of variation of cane yield was lower than that of the double controls in paddy fields and intermediate between those of the double controls in dry lands.These findings indicate that Yunrui 14 658 has high yield po-tential,strong resistance,and perennial ratooning ability,root,and the environment had little effect on sugar yield.It was an ideal new sugarcane line with high yield and high sugar resistance.The cane yield and sugar yield of Yunrui 14599 in dry land were significantly higher than that of Liucheng 05-136(CK2).The high stability coefficient of sugar yield in paddy field and dry slope land was higher than that of double control.The high stability coefficient of average cane yield in paddy field and dry slope land was between the double control.The coefficient of variation of cane yield and sugar yield in paddy field was lower than that of double control,and that in dry land was higher than that of double control.The resistance to ratooning was excellent,indicating that it was suitable for paddy field planting.关键词
