早熟、优质、耐贮梨新品种新梨7号选育研究

以库尔勒香梨为母本,早酥梨为父本,有性杂交选育成新梨７号品种。该品种同时兼备优质、早熟与耐贮藏性;该品种遗传了父本的早熟性,比父本更早熟１５~２０ｄ,盛花期~果实可食期约８０~９５ｄ,属于早熟品种;且遗传了母本品质性状的质地酥脆、耐贮、清香、阳面红晕,比母本果个大,果心小。果柄木质化,丰产抗风。新梨７号果实贮藏期的可溶性固形物、果实重量、果实硬度和果实前期腐烂率的变化与库尔勒香梨基本相似,但耐热能力高于母本。凡适宜香梨、早酥、苹果梨和巴梨种植的地区,都适宜该品种的种植。

Breeding of New Pear Variety Xinli No.7 with Characters of Early Maturity,Best Quality and Long Storage Life

The Xinli No.7 pear variety was derived from the cross of Kuerle Xiangli × Zaosu pear varieties. This is an inno-vation of Chinese Pear germplasm;Its outstanding characters are excellent eating quality,early maturity and long storage life.Its early maturity was inherited from the male parent, but earlier than the latter by 15~20 days. Comparing with the femaleparent, its fruit size is bigger and with a smaller fruit core, but with the same redish skin and crisp, juicy and aromatic flesh.The trees are productive and resistant to wind and heat. During storage, the changes of flesh firmness, the soluble solids con-tent,fruit weight, and fruit rot rate are similar to its female parent.It is believed that this variety could be planted in the areaswhere the Kuerle Xiangli,Zaosu,Pingguoli and Bartlett pear can be grown.
