Niigata prefecture is famous for rice named Koshihikari. Production of rice in Niigata prefecture is the highest in Japan, and it is thought that Koshihikari made in Niigata prefecture is most delicious rice in Japan. Furthermore, Koshihikari made in Uonuma city and Minamiuonuma city is more delicious. Because this area is very hot in daytime by foehn phenomena and not hot in night. Koshihikari made in Fukui prefecture. At first, one kind of rice named Etsunan 17 was developed, but it was not adopted in Fukui prefecture in spite of birth place of it. Because Etsunan 17 had bad result in the test. However, Niigata prefecture and Chiba prefecture adopted Etsunan 17. Niigata prefecture was asked to name Etsunan 17 by Fukui prefecture, and Niigata prefecture named it Koshihikari.
Strong
points of Koshihikari are good
balance of dextrin and protein, and good amount of moisture. Koshihikari has good balance of amylose,
amylopectin and protein. Amylose and amylopectin are ingredients of dextrin. The
higher proportion of amylose in the rice, the less glutinous the rice becomes. The
higher proportion of amylopectin, the more glutinous the rice becomes. And the amount
of moisture in the rice is adjusted to best amount by farmer. So Koshihikari is very delicious and Koshihikari’s feeling in the mouth is
chewier than other rice, and the rice don’t become taste bad when the rice get
cold.
But Koshihikari has bad point. It is very
difficult to cultivate Koshihikari. There
are some reasons make cultivating Koshihikari
difficult. Koshihikari is easy to
fall down because the stem of it is tall and the ears of it are heavy. When rain
falls heavily and wind blows heavily, Koshihikari
will fall down. If Koshihikari fall
down, people raise it by their hands when they harvest it, so harvesting it
become more difficult. People put on manure divide into several times so that
the ears of Koshihikari don’t become
heavy. Moreover, Koshihikari is vulnerable
to rice blast. Rice blast is one of illness of rice plants, and it is the most
terrible illness of rise plants. If Koshihikari
contract rice blast, size of harvest will decrease and taste of rice become badly.
These days, Koshihikari was improved
and new kind of Koshihikari named Koshihikari BL was developed. Koshihikari BL is almost the same as Koshihikari, but Koshihikari BL is not vulnerable to rice blast. BL is an
abbreviation of Blast resistance Lines.
People overcome these difficulties, and they
make the very delicious rice.
