1 An Lijia Professor of Dalian University of Technology President of Lanfeng Agricultural Technology co., LTD Investigation and Analysis of Dominant Blueberry Varieties for Different Regions in China

2  Commercial value  Flavor  Good storage quality  Large size berry  High yield  Regional adaptability  Heat or cold tolerance  High yield and consistent productive ability  Continuous harvest with selected varieties The basis of investigation and analysis on dominant varieties for different region in China

3 Major blueberry production areas in China

4  Northern China to Central China  Liaoning  Shandong  Central China  Anhui  Jiangsu  Hubei  Shanxi  Central China to Southern China  Sichuan  Chongqing  Zhejiang Main blueberry production regions in China

5  Growth habits  2 m tall;  Moderate vigor , open ;  yield 1000kg per acre.  Commercial value  Fruit ripen early;  Average fruit weight 1.9g;  Excellent flavor;  Fruit stores and ships well;  The preferred selective variety for fresh markets. ‘O’neal’— Early season southern highbush variety

6  Suitable areas  The dominant variety for greenhouse growth in Liaoning and Shandong.  The dominant variety for field culture and plastic tunnel culture in southern Yangtze river.  Growing techniques  Bushes are weak vigor, strengthen irrigation and nutrition management are required;  Fruit cracking occurs easily in rainy season, rain shelters are required in the field.

7 Misty’—Early to mid season southern highbush cultivar  Growth habits  2 m tall;  Vigorous, upright, open;  Yield1000kg berry per acre.  Commercial value  Early to mid season variety;  Average berry weight of 1.65g;  Excellent shipping/storage quality;  Preferred selective variety for fresh market.

8  Suitable areas  Similar to O’neal;  Cross pollination is available with O’neal.  Cultural practices  Percentage of fruit setting is high. Heavy pruning is required to avoid over-cropping.

9 ‘ Legacy’—Mid-season southern highbush variety  Growth habits  2m tall;  Very vigorous; Open, Upright;  Consistently productive;  Yield 1000kg berry per acre.  Commercial value  Mid-season variety;  Average berry weight of 2.0g ;  Shipping/storage quality is well ;  The preferred selective variety for fresh market sales.

10  Suitable areas  The dominant variety in Yangtze river basin and southern Yangtze river areas such as Zhejiang province.  Cultural practices  High percentage of fruit setting, an appropriate pruning is required before blooming to maintain berry size.

11 ‘NanDa’—Early to mid season southern high bush variety  Growth habits  2m tall;  Vigorous, semi-open ;  Yield 1000kg per acre.  Commercial value  An early to mid season variety;  Fruit ripen 3-5 days early than Legacy;  Average berry weight of 1.9g;  Excellent shipping/storage characteristics;  The preferred selective variety for fresh market sale.

12  Suitable areas  The dominant variety for areas from Yangtze river basin to Zhejiang.  Cultural practices  Cross pollination is available with Legacy.  Percentage of fruit setting is high; Pruning before blooming could increase the berry weight.

13 Nanjin’—Early to mid-season southern high bush variety  Growth habit  2m tall; Very vigorous, open;  Excellent stress tolerant ability, develop normally on poor soil condition;  Very productive; Yield average 1500kg per acre.  Commercial value  Early to mid-season variety;  Ripen 8 days later than O’neal;  Average berry weight of 1.3g;  High sugar content ( %);  Good flavor ;  Suitable for both fresh and processing use.

14  Suitable areas  The dominant variety for areas from Southern Yangtze river to Zhejiang province.  Cultural practices  The percentage of fruit setting is very high; Pruning severity before blooming could increase berry size.  Delaying harvest operation could be adopted to increase sugar content of fruits when used for processing.

15 Duke’—Early season northern high bush variety  Growth habits  2m tall;  Moderate vigorous;  Erect, open;  Yield 1000kg fruit per acre.  Commercial value  Fruit ripens early;  Average berry weight of 2.1g;  Excellent shipping/storage quality;  Excellent flavor;  The preferred selective cultivar for fresh market.

16  Suitable areas for planting The dominant variety for greenhouse and field culture in Liaoning and Shandong province.  Cultural practices Perform poorly when soil pH and fertility are not optimal. Strengthen management is required on irrigation and fertilization.

17 ‘Lanyuan’—Early to mid-season northern high bush variety  Growth habits  2m tall;  Vigorous, open;  Good productive ability;  Yield 1000kg per acre.  Commercial value  Early to mid season variety;  Average berry weight of 2.0g ;  Excellent shipping/storage quality;  Good flavor;  Preferred selective variety for fresh market sale.

18  Suitable areas  The dormant variety for field culture in Yangzi river basin;  The dormant variety for greenhouse growth in Liaoning and Shandong.  Cultural practices  The percentage of fruit setting is very high; Pruning severity before blooming could increase berry size.

19 ‘Brigitta’ —Mid season northern highbush variety  Growth habits  2m tall;  Very vigorous, upright, open;  Yield 1000kg berry per acre.  Commercial value  A mid-season variety;  Average berry weight of 2.1g;  Excellent shipping/storage quality;  Excellent flavor;  Preferred selective variety for field culture intended for fresh Market.

20  Suitable areas The dormant variety for Yangtze river basin and part of southern Yangtze river.  Cultural practices The percentage of fruit setting may be reduced when suffering from high or low temperature. Need to pay attention to temperature management in blooming season

21 ‘Bluecrop’—Mid-season northern highbush variety  Growth habits  2m tall;  Vigorous, upright, open;  Yield 1000kg per acre.  Commercial value  Mid-season variety;  Average berry weight of 2.1g;  Good shipping/storage quality;  The optimal variety for field culture intended for fresh Market.

22  Suitable areas The most competitive variety for field culture in Liaoning and Shandong province.  Cultural practices Tends to overproduce if pruned incorrectly; Strengthening pruning before blooming could increase berry weight.

23 ‘Elliott’—Late season northern highbush variety  Growth habits  2m tall;  Moderate vigorous, erect;  Yield 1000kg per acre.  Commercial value  Very late season;  Average fruit weight of 1.8g;  Good shipping/storage quality;  The preferred selective cultivar for field growth.

24  Suitable areas The dominant cultivar for field culture in Liaoning.  Plant technique Elliott has moderate vigor and adequately pruning is required to retain bush growth and berry size.

25 Basic principles of variety selection for blueberry growers  Good commercial value  Select dominant varieties as leading varieties  Select dominant varieties as pollinator  Avoid using multiple varieties when establishing blueberry orchard
