Abstract:

In 1998, we introduced a Panicum maximum 'TD58' cultivar from Australian. Then after, its botanical characters and adaptability were evaluated. After variety comparing test, production tests in different region, a new cultivar was selected and named as P. maximum 'Reyin NO.19' in 2007. The test results showed its annual hay yield reached 201753.02 kg·hm-2, and seed yield reached to 800.05 kg·hm-2 per year. 'Reyin NO.19' has excellent comprehensive characters in compared with control in nutrition value, cold, shade and drought resistance, later flowering stage, is a new forage variety that suitable to be planted in tropical and subtropical area of China.
