Evaluation of Feeding Potential of Pterocypsela Indica in Northern Fujian

In order to select new varieties of Pterocypsela indica that are suitable for cultivation in Northern Fujian, the agronomic characters of Pterocypsela indica in Northern Fujian were evaluated through field experiments. The results showed that compared with the control Original population and Lactuca indica L. Mengzao, the longest growth period of Pterocypsela indica in Northern Fujian was 298 d, which belonged to the late maturing line. The fresh grass yield and hay yield of Pterocypsela indica in Northern Fujian were both the highest and significantly highest than that of the control Original population and Lactuca indica L. Mengzao. The annual average fresh grass yield was 47618.6 kg·hm^-2, and the annual average hay yield was 4552.2 kg·hm^-2. There were more leaves in Pterocypsela indica in Northern Fujian, and the leaf dry weight accounted for 89.29% of the total weight of leaf stems. The average seed yield of 68034 g·hm^-2 was highest than that of the control Original population Lactuca indica L. Mengzao. Based on the comprehensive analysis, Pterocypsela indica in Northern Fujian had the characteristics of long growth period, high grass yield, high proportion of leaf dry weight to the total weight of leaf stems, and good resistance, which was suitable as feed grasses in Northern Fujian.
