Haplotype structure analysis of a locus associated with fruit skin type on chromosome 8 in Japanese pear

ABSTRACT The new SCS421 Carolina cultivar, belonging to the Pyrus pyrifolia var. culta species, is classified as an Asian pear type or more specifically Japanese pear type. It was obtained from the Kousui x Osanijisseiki crossing made at Epagri / Caçador Experimental Station. Its flowering occurs from the second half of September to mid-October, similarly to Housui cultivar. According to preliminary results, ‘Yali’ and ‘Housui’ may be used as pollinators. The harvest takes place in the first half of February and production is above 20 t / ha. Plants produce more rounded and symmetrical fruits compared to Housui cultivar. The fruit skin is golden, the pulp is crispy, soft, sweet, very juicy and slightly aromatic. Fruits can be stored for up to four months in conventional cold storage. The incidence of scabies and dry branch diseases in the field has not been recorded. It is recommended for cultivation at colder regions of southern Brazil.

Lower Temperature

Dark browning of fruit skin of Japanese pear `Niitaka' (Pyrus pyriforia) is a physiological disorder during storage. Very higher rates of dark browning were observed in bagged pears, and in the orchards under higher humidity during the maturing season. Also the factors, such as higher humidity and lower temperature in storage room increase the dark browning. Dark browning is a different physiological disorder with the sugerficial scold of apples, which associated with conjugated trienes, oxidation products of alpha-farnesenes. The dark browning was controlled by dipping the harvested pears into 1,000 ppm diphenylamine (DPA) solution for 5 seconds before storage.

Long Time

In recent years, the electron microscope has been significantly improved in resolution and we can obtain routinely atomic-level high resolution images without any special skill. With this improvement, the structure analysis of organic materials has become one of the interesting targets in the biological and polymer crystal fields.Up to now, X-ray structure analysis has been mainly used for such materials. With this method, however, great effort and a long time are required for specimen preparation because of the need for larger crystals. This method can analyze average crystal structure but is insufficient for interpreting it on the atomic or molecular level. The electron microscopic method for organic materials has not only the advantage of specimen preparation but also the capability of providing various information from extremely small specimen regions, using strong interactions between electrons and the substance. On the other hand, however, this strong interaction has a big disadvantage in high radiation damage.
