Abstract

|
|
This study was carried out to obtain basic information on variety selection for the utilization of whole crop rices(WCR) at National Institute of Crop Science, RDA, in 2004.
Fifteen varieties and elite line were evaluated on feed value such as dry matter yield(DMY), crude protein(CP), acid detergent fiber(ADF), neutral detergent fiber(NDF) and total digestible nutrients(TDN).
The dry matter yields were ranged from 13.23 to 17.83ton per ha, the highest yielding varieties were Sobibyeo(16.98ton/ha) in Japonica type, SR22060 (17.83ton/ha) in New plant type, Hangangchalbyeo(17.66ton/ha) in Tongil type.
Suweon 468 showed the highest value in the RFV and TDN content among the varieties, and Suweon 468, Suweon 498, Suweon 490 and SR22058 were chosen to have the high feed values through cluster analysis.
The dry weight(grain) was found to be positively related with percent of the ripened grain, 1,000 grain weight and CP. TDN content was found to be positively related with CP, but negatively related with NDF and ADF. RFV was found to be negatively related with plant height, NDF and ADF.
The promising rice varieties for WCR were Suweon 468, Suweon 498, Suweon 490 and SR22058 on the basis of CP, TDN and DMY.
