Transitions in Leading Japanese Pear Cultivars and Current Status of Pear Breeding at NIFTS, NARO, Japan

Headspace Volatiles of Selected Melon, Pear and Carrot Cultivars

Herein, we report on the results of solventand sorbent-free HS-GC-MS (headspace – gas chromatography – mass spectrometry) analysis of the headspace volatiles (HSVs) of fruits of cultivated melon (Cucumis melo L. cultivar “ananas dinja” [pineapple melon]) and pear (Pyrus communis L. cultivar “Julska lepotica” [the beauty of July]), as well as of underground parts of carrot (Daucus carota L. cult...

Comparative Transcriptome Analysis of the Less-Dormant Taiwanese Pear and the Dormant Japanese Pear during Winter Season

The flower bud transcriptome in the less dormant Taiwanese pear 'Hengshanli' and high-chilling requiring Japanese pear strain TH3 subjected to the same chilling exposure time were analyzed during winter using next-generation sequencing. In buds sampled on January 10th and on February 7th in 2014, 6,978 and 7,096 genes, respectively, were significantly differentially expressed in the TH3 and 'He...

Diversity of odor-active compounds from local cultivars and wild accessions of Iwateyamanashi (Pyrus ussuriensis var. aromatica) revealed by Aroma Extract Dilution Analysis (AEDA)

Some local cultivars and wilds of Iwateyamanashi (Pyrus ussuriensis var. aromatica) that grows wild in Northern Tohoku, Japan have good aromatic fruit. Iwateyamanashi may be valuable germplasms as a donor of odor compounds in breeding of Japanese pear (Pyrus pyrifolia), because almost all Japanese pear cultivars have faint odor. Fruits odors from a local cultivar 'Sanenashi', a wild accession (...

Breeding, genetics, and genomics of fruit trees

Because most regions of Japan are in the temperate climate zone, many deciduous and evergreen fruit crops are cultivated in Japan. In addition to fruit cultivation in the temperate zone, some southern areas, such as the Ryukyu Islands that stretch from Kyushu to Taiwan, are at the northern limits for tropical fruit production without the need of artificial heating. At present, annual fruit prod...
