This variety is a non-glutinous rice variety, suitable for whole crop silage (WCS), with early maturing, excellent lodging tolerance, and high yielding ability. Yumeaoba was bred from the progeny of a cross between Jyou 321 and Ouu 331 (named as Fukuhibiki later) in 1990. From the F11 progenies, we selected one promising line and named Hokuriku 187, and submitted the line to various locations for evaluating local adaptability. Hokuriku 187 was officially registered as Paddy Rice Norin 398 in MAFF and in 2004 it was named as Yumeaoba. Agronomic characters of Yumeaoba evaluated are as follows. Its heading date is slightly later than Fukuhibiki and 4 to 5 days earlier than Kusayutaka. The culm length is 9cm longer than that of Fukuhibiki, whereas it is 8cm shorter than that of Todorokiwase. Its panicle length is slightly longer than Fukuhibiki and the panicle number is significantly less than those of Fukuhibiki and Todorokiwase. The plant type of this variety is classified into panicle weight type. The shape of brown rice is slightly slender and 1000-kernel weight is estimated to be about 26.5 g. The dry matter yield in the yellow-ripe stage is more than those of Fukuhibiki and Todorokiwase in transplanting culture and direct sowing in flooded paddy fields. The total digestive nutrients (TDN) in the yellow-ripe stage are estimated to be nearly 60%, which corresponds to that of timothy grass in its heading stage. Yumeaoba is estimated to possess true blast resistance genes, Pita-2 and Pib, but its field resistances for leaf blast and panicle blast are not known. To stripe virus disease and bacterial leaf blight, this variety appears to be resistant. Yumeaoba is tolerant to lodging and suitable for direct sowing in flooded paddy fields. Its tolerance to sprouting is moderate, but its cool weather tolerance isweak. Thus, Yumeaoba can be grown in regions from middle-Tohoku area to Kyushu area for the use of WCS.}, pages = {1--23}, title = {水稲新品種「夢あおば」の育成}, volume = {7}, year = {2006}, yomi = {ミウラ, キヨユキ and ウエハラ, ヤスキ and コバヤシ, アキラ and オオタ, ヒサトシ and シミズ, ヒロユキ and ササハラ, ヒデキ and オオツキ, ヒロシ and ゴトウ, アキトシ and シゲムネ, アキコ} }
