内容記述 |
'Nashi chuukanbohon nou 1 gou' is a new mid- to late-maturing cultivar of Japanese pear (Pyrus pyrifolia Nakai) with smooth skin, released in 2002 by the NARO Institute of Fruit Tree Science (NIFTS). The Japanese name of the cultivar is translated as "the first registered clone that was shown to be useful in Japanese pear crossbreeding". The cultivar was released from the breeding program with funds from the Ministry of Agriculture, Forestry and Fisheries in Japan. 'Nashi chuukanbohon nou 1 gou' originated from the selfing of 'Osanijisseiki' in 1980. 'Nashi chuukanbohon nou 1 gou' was selected as a homozygote of S^sm_4, a self-compatible haplotype of Japanese pear, in 1991 from cross-pollination tests. Furthermore, self-compatible offspring were obtained efficiently by using 'Nashi chuukanbohon nou 1 gou' as the parent in cross-pollination experiments from 1998 to 2000. 'Nashi chuukanbohon nou 1 gou' was registered as No.16164 under the Plant Variety Protection and Seed Act of Japan on March 5, 2008. The tree vigor of 'Nashi chuukanbohon nou 1 gou' is not as strong as 'Osanijisseiki' ; however, the amount of fruit spurs and axillary flower buds are nearly the same for the two cultivars. 'Nashi chuukanbohon nou 1 gou' is self-compatible with a level of self-fruitfulness as high as that for 'Osanijisseiki'. 'Nashi chuukanbohon nou 1 gou' blooms later than 'Osanijisseiki', and the two cultivars ripen at almost the same time. 'Nashi chuukanbohon nou 1 gou' is resistant to black spot disease, and there are no serious problems with diseases or insect pests when trees are subjected to standard spraying programs. The fruit of 'Nashi chuukanbohon nou 1 gou' is round in shape, weighs about 200g, and is smaller than the fruit of 'Osanijisseiki'. An intermediate amount of suberin develops on the skin surface of fruit when grown under non-bagging culture conditions. The flesh hardness of 'Nashi chuukanbohon nou 1 gou' is 5.3 lbs., being a little harder than that of 'Osanijisseiki'. The soluble solids content and the pH in 'Nashi chuukanbohon nou 1 gou' fruit juice average around 12% and 4.7, respectively, both of which are almost as high as those of 'Osanijisseiki'. Pistils from the S_8 haplotype accept the pollen of 'Nashi chuukanbohon nou 1 gou' to the same extent as the S_2, S_3, S_5, S_6, S_7, S_9 and S_k haplotypes, suggesting that S_8S^sm_4 is self-compatible. The expected ratios of self-compatible offspring yielded from crosses between self-incompatible cultivars and 'Nashi chuukanbohon nou 1 gou' are almost twice as high as those from crosses between self-incompatible cultivars and the S^sm_4 heterozygote. One notable exception arises from the incompatibility between S^sm_4 pollen and the S_1 as well as the S_4 pistils. 'Nashi chuukanbohon nou 1 gou' is expected to be a useful genetic material for efficiently obtaining self-compatible progeny. |
