Abstract In
order to choose suitable varieties with high yield and good quality for
cultivation, 10 lucerne varieties, including six foreign ones
(‘WL-525HQ’, ‘WL-414’, ‘WL-323’, ‘Italian’ lucerne, ‘Sitel’, and
‘Vernal’) and four domestic ones (‘Wudi’ lucerne, ‘Aohan’, ‘Zhongmu
No.1’, and ‘Inner Mongolian’ lucerne), were studied in Zhengzhou, Henan
Province, China, in 2001 and 2002 using a randomised block design with
three replications. Each plot was cut four or five times each year over
the 2-year period to evaluate herbage production of the tested
varieties. ‘WL-525HQ’, ‘Sitel’, and ‘WL-414’ were the best, with
relatively high plant height, large leaf/stem ratio, and dry matter
herbage yield. Cutting times had a significant effect on dry matter
herbage yield, with the highest yield in the first cut and the lowest
in the fifth. Correlation analyses showed that plant height was
significantly positively related with dry matter herbage yield. Close
relationships were found among annual dry matter herbage yield, dry
matter yield and protein production in the first cutting, leaf/stem
ratio, and plant height. These results suggest that using leaf/stem
ratio and dry matter herbage yield at the first cut could predict the
general productivity of a lucerne variety.
