| Abstract/Contents: | "A new Italian ryegrass (Lolium multiforum Lam.) cultivar, Niodachi, developed by the National grassland research institute was registered as Norin No. 17 of Italian ryegrass and released by the Ministry of Agriculture, Forestry and Fisheries of Japan in 1995. This cultivar was developed by mass and maternal line selection methods for high lodging resistance and high seed productivity using "Waseaoba" as a breeding material (Fig. 1). "Niodachi" is an early heading cultivar (Table 4) with high seed productivity (Table 18), and it has higher lodging resistance than other leading commercial cultivars of that heading, such as "Waseaoba", "Tachiwase", and "Tachimasari", which are also characterized with good lodging resisitance (Table 5,19). The high lodging resistance of this cultivar is considered to be due to its shorter stem than that of other cultivars (Table 8). "Niodachi" shows high dry matter digestability according to the analysis by in-vitro cullulase method and lower percentage of acid detergent fiber content than those of other cultivars at the first cutting (Table 17). The forage yield of "Niodachi" is similar to other early heading cultivars, and that is lower in Chugoku and northern Kyushu district (Table 2, 3). However, high digestable dry matter productivity per unit area is expected due to the high dry matter digestibilty and the low harvesting losses in the harvesting machinery, because of its high resistance to lodging. "Niodachi" is adaptable to the south western part of Japan to the south of the Kanto district, since this cultivar does not have enough resistance to snow mold diseases (Table 7). It can be grown until sowing time of summer forage crops such as maize and sorghum and should be suitable for hay or grass silage making which is mowed and round-baled by the harvesting machinery. As this cultivar is susceptible to crown rust (Puccinia coronata Corda f. sp. Lolli Eriks, Table 6), it is advisable that in the aftermath it should be harvested before being severely damaged by this disease which might be prevailing in late spring." |
