1. The new strawberry variety 'Marihime' for forcing culture was released in 2008 by crossing between 'Akihime' and 'Sachinoka' in 2003. 2. 'Marihime' is moderately prostrate; the plant is higher than 'Sachinoka' and lower than 'Akihime'. GA application and long day treatment are not necessary for forcing culture of 'Marihime', because the plants do not become dwarf even in winter. 3. In 'Marihime', the flower bud of the primary cluster differentiate in mid-September in Kinokawa, Wakayama Pref., which is a few days earlier than' Sachinoka' and a few days later than 'Akihime'. The harvest start at early December, two weeks earlier than 'Sachinoka'. The secondary flower bud of 'Marihime', however, appear later than' Sachinoka'. 4. The early yield of 'Marihime' until January is equal to or higher than that of' Akihime' and 'Benihoppe'. The total yield until April is higher than, 'Akihime' and 'Sachinoka' and equal to 'Benihoppe'. The percentage of normal fruit is high because irregularly shaped fruits are produced very few. The average weight of marketable fruit is more than 18 g, which is bigger than 'Sachinoka' and almost equal to 'Benihoppe', 5. The sugar content of 'Marihime' fruit is as constantly high as 'Sachinoka'. The acidity of 'Marihime' fruit is lower than 'Sachinoka' and higher than 'Akihime'. 6. 'Marihime' is susceptible to anthracnose, Fusarium wilt and powdery mildew as well as 'Sachinoka'. Self-topping, a determinate growth habit, occur in 'Marihime' as well as 'Benihoppe'.
