BREEDING OF NEW PEAR WINTER CULTIVAR 'PANDORA'

Breeding of new rice cultivar ‘Tohoku 194’ with ‘Sasanishiki’-type good eating quality of cooked rice

Cooked rice of 'Sasanishiki' is soft and not as sticky as those of Japanese leading cultivars 'Koshihikari' and 'Hitomebore'. As a method for efficient selection of a breeding line having a good eating quality like that of 'Sasanishiki', the use of physical properties of cooked rice and cooking quality was examined. There were differences of physical properties of the surface layer, starch-iodi...

Advances in the Breeding of Tree Peonies and a Cultivar System for the Cultivar Group

Tree peonies native to China have become an internationalized ornamental plant and are widely cultivated in many countries in Asia, America, Europe and Australia. Breeding starting from domestication of wild plants through selection of bud mutations and seedlings to hybridization has been done for about 1500 years. At present a few thousand cultivars are cultivated globally in gardens or propag...

Effects of nitrogen and chlormequat on growth and grain yield of winter barley cultivar valfajr

Development of cultivar-specific DNA markers based on retrotransposon-based insertional polymorphism in Japanese pear

We developed retrotransposon-based insertional polymorphism (RBIP) markers based on the long terminal repeat (LTR) sequences of copia-like retrotransposon Ppcrt4 and flanking genome sequences, which were derived from 454 sequencing data from Japanese pear (Pyrus pyrifolia) 'Hosui'. Out of 40 sequences including both LTR and flanking genome regions, we developed 22 RBIP markers and used them for...

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...
