Comparative study on the production performance of 13 Stylosanthes germplasms
摘要
Abstract
In order to screen Stylosanthes varieties of excellent comprehensive properties,the adaptability of 1 3 Stylosanthes germplasms were studied by testing the height,survival rate,stem leaf ratio,anthrax disease, hay yield,seed yields,1000-grain weight,and nutrition components from 2011 to 2014;the production per-formances were compared and evaluated by membership function.The results showed that their initial blosso-ming stage was from September to November.The survival rate of TPRC2001-84 was the highest,up to 72.6%followed by TPRC 2001-81 with 56.6%.The 13 Stylosanthes germplasms were all resistant to anthracnose. Forage DM yield of TPRC 2001-84 was the highest,up to 15 968 kg?ha-1,followed by TPRC2001-81 and Reyan No.20,12 206,and 12 724 kg?ha-1,respectively.It was also found that the highest seed yield was in TPRC 2001-85,up to 56.7 kg?ha-1,and the highest crude protein content was in Reyan No.21 with up to 21.57%.The highest crude fat and phosphorus content was in Reyan No.20 and Reyan No.21.The highest cal-cium content was in Reyan No.21.The highest potassium content was in TPRC 2001-85.Therefore,among all the Stylosanthes germplasm,TPRC 2001-84,Reyan No.21,TPRC 2001-85,and TPRC 2001-1 had been found to have excellent production performance and were suitable for promotion and cultivation in the tropical area.关键词
