Preliminary evaluation of Crisp Sweet Pomelo,a newly discovered germplasm resource in Jiande,Zhejiang
Crisp Sweet Pomelo is a newly discovered pomelo germplasm resource in Jiande City,Zhejiang Province.To understand the characteristics and production application value of Crisp Sweet Pomelo,according to the requirements of the description specification,its botanical characteristics,biological characteristics and stress resistance were observed in the field.The quality indicators such as soluble solids were sampled and determined,and the yield was assessed at harvest period.The results showed that the Crisp Sweet Pomelo could withstand the low temperature of-5 ℃.The leaf is full margin,with no wavy serration.It is self-compatible with strong bearing ability,no need for pollination trees and artificial pollination.There is a ring on the top of the fruit.It is seedy with up to 116 full seeds per fruit at mature.Full flowering period was in early May,with fruit mature in mid-November.The pulp texture was tender,moderate sweet and sour,no bitter taste,no odor,with edible rate of 44.7％,juice rate of 35.6％,soluble solid content of 14.1％,titratable acid content of 0.6 g/100 g,vitamin C content of 78.8 mg/100 mL.The fruit cracking rate before harvest was moderate,with cracking rate of 15％-20％.The average single fruit weight was 1,620 g.4-year-old tree produced 44.1 kg fruits per plant and 2,646 kg fruits per 667 m2.Crispy Sweet Pomelo is a high-quality pomelo germplasm resource,with good potential for further research and promotion.
