Breeding of new rice cultivars 「Akinokirameki」 and 「Tsubuzoroi」

「Akinokirameki」 is a non-glutinous rice cultivar developed by Akita Prefectural Agricultural Experiment Station. It is a selection from the cross Iwanan 16 / Akikei 483 in 1999. Fsub(1) plants were grown in the field in 2000, and individual selection of Fsub(2) was carried out in 2001, followed by line selection. An application for registration was made in 2012, and 「Akinokirameki」 was released in Akita prefecture as a recommended cultivar in 2013. The agricultural characteristics of "「Akinokirameki」 are as follows; 1) Heading and maturing are at the same time of 「Dewahikari」. It belongs to the early maturing group at Akita. 2) The culm length is equal to that of 「Takaneminori」, and plant type is a panicle-number type. Its lodging resistance is equal to that of 「Takaneminori」. 3) Yield potential of 「Akinokirameki」 is greater than that of 「Takaneminori」 and 「Dewahikari」, equal to that of 「Akitakomachi」. 4) Its resistance to the leaf blast is similar to that of 「Takaneminori」. Its resistance to the panicle blast is superior to that of 「Takaneminori」 and 「Akitakomachi」. The resistant gene is assumed to be “+”. Resistance of 「Akinokirameki」 to cool temperature induced sterility is superior to that of 「Takaneminori」 and 「Akitakomachi」. 5) Visual grain quality of 「Akinokirameki」 is equal to that of 「Akitakomachi」. 6) Eating quality of 「Akinokirameki」 is equal to that of 「Akitakomachi」. 7) 「"Akinokirameki」 appears to have an adaptation to mountainous area in Akita prefecture. 「Tsubuzoroi」 is a non-glutinous rice cultivar developed by Akita Prefectural Agricultural Experiment Station. It is a selection from the cross Akita 59 / Ou 366 in 1998. Fsub(1) and Fsub(2) plants were grown in a green house in 1999, and panicle selection of Fsub(3) and panicle line selection of Fsub(4) was carried out in 2000 and 2001 respectively, followed by line selection. An application for registration was made in 2012, and 「Tsubuzoroi」 was released in Akita prefecture as a recommended cultivar in 2013. The agricultural characteristics of 「Tsubuzoroi」 are as follows; 1) Heading and maturing are at the same time of 「Haenuki」. It belongs to the late maturing group at Akita. 2) The culm length is equal to that of 「Hitomebore」 and 「Akitakomachi」, and plant type is a intermediate type. Its lodging resistance is superior to that of 「Hitomebore」 and 「Akitakomachi」. 3) Yield potential of 「Tsubuzoroi」 is greater than that of 「Haenuki」, 「Hitomebore」 and 「Akitakomachi」. 4)「Tsubuzoroi」 has a Pia gene for true resistance to blast disease. Both its resistance to the leaf blast and to the panicle blast is superior to that of 「Haenuki」, 「Hitomebore」 and 「Akitakomachi」. Resistance of 「Tsubuzoroi」 to cool temperature induced sterility is equal to that of 「Haenuki」 and 「Hitomebore」. 5) Visual grain quality of 「Tsubuzoroi」 is equal to that of 「Hitomebore」 and 「Akitakomachi」. 6) Eating quality of 「Tsubuzoroi」 is equal to that of 「Akitakomachi」. 7) 「Tsubuzoroi」 appears to have an adaptation to flat area in Akita prefecture.
