 note = {A new rice variety, "Kusayutaka" is a non-glutinous rice variety suitable for whole crop silage (WCS) with extremely large grain and high-yielding ability, Hokuriku Research Center of the National Agricultural Research Center (former Hokuriku National Agricultural Experiment Station) of National Agricultural Research Organization (NARO) in 2002. In the breeding program for extremely high-yielding ability, "Kusayutaka" was bred from the progeny of the crossing between Chugoku 105 and Hokuriku 130 (named later as "Oochikara") in 1987. A selected promising line was named Hokuriku 168 at the F_7 generation to be submitted to local adaptability trials at various locations. Hokuriku 168 was registered as Paddy Rice Norin 383 by the Ministry of Agriculture, Forestry and Fisheries and was named as "Kusayutaka" in 2002. This variety has the same heading stage of "Kinuhikari", but maturing stage is slightly later than that of "Kinuhikari". Culm length is 3-4cm longer than that of "Kinuhikari", panicle length is slightly longer than that of "Kinuhikari", and panicle number is evidently less than that of "Kinuhikari", and plant type is panicle weight type. This variety is highly yielding ability, and total weight and yield of brown rice are more than that of "Kinuhikari". Brown rice is slightly slender and extremely large, and thousand-kernel weight is about 35g. Grain quality and eating quality are evidently inferior to that of "Kinuhikari". The total digestible nutrients (TDN) of this variety in yellow-ripe stage is estimated nearly 60% (DM), value is corresponding with that of grass in heading stage, such as timothy, and WCS is adapted feed of livestock, This variety seems to possess true blast resistance genes Pia and Pik, and field resistance of blast is moderate. Tolerance to sprouting is moderately week, and its cool weather tolerance is weak. This variety is tolerance to lodging, and is adapted to direct sowing for low cost rice cultivation. "Kusayutaka" can be grown in a region from Middle-Tohoku area to Kyushu area of Japan for uses of WCS.},
