Abstract

Abstract: ‘Rongzhen 4’is a new Luffa cultivar for balsam pear rootstock. It is made by crossing 24-1 as female parent and 61-3 as male parent. Its parents are highly resistant to Fusarium wilt. It has good grafting compatibility with balsam pear. The grafted seedlings have significantly increased yields,low disease index and incidence. Field trials using‘Zaoliang’as scion showed early yield of 23 778 kg · hm^-2 and total yield of 83 613 kg · hm^-2,representing 13.4% and 11.3% increases over‘Rongzhen No. 1’,respectively. This new rootstock has been demonstrated on 200 hm²,providing a promising solution for sustainable balsam pear production.
