内容記述 |
'Natsuyu', a new diploid variety of red clover (Trifolium pratense L.), was developed by the National Agricultural Research Center for Hokkaido Region and Hokkaido Prefectural Konsen Agricultural Experiment Station. 'Natsuyu' was bred by random crossing of four maternal lines that were selected from 44 varieties/lines. The characteristics of 'Natsuyu' are low competitive ability for timothy and good over-wintering ability. The yield ability for dry matter of 'Natsuyu' was similar that of 'Hokuseki'. In the mixed sown sward, the yield of timothy with 'Natsuyu' in the third year was 20％ higher than that of timothy with 'Hokuseki'. The red clover ratio of 'Natsuyu' was lower than that of 'Hokuseki' and higher than that of 'Kurano'. It seemed that the reasons of the low compe-titive ability of 'Natsuyu' for timothy were the lower degree of flowering and the lower plant height in the second crop. 'Natsuyu' showed better vigorous and re-growth in the early spring than 'Hokuseki' and' Kurano'. It also showed stronger cold hard-iness than 'Hokuseki'. These results indicated that 'Natsuyu' had good overwintering ability. Since the flowering date of 'Natsuyu' was similar to that of 'Hokuseki', 'Natsuyu' consi-dered to be an early flowering type. Thegrowth type of the first autumn was more rosette type than 'Hokuseki' and more flow-ering type than 'Kurano'. 'Natsuyu' had more resistance than 'Hoku-seki' and 'Kurano' to powdery mildew and sclerotinia crown and stem rot. The toleranceto black leaf bright and rust of 'Natsuyu' was the same as that of 'Kurano' and slight weaker than that of 'Hokuseki'. 'Natsuyu' showed similar seed yield and chemical composition compared to 'Hokuseki'. |
