Comparative Study on Yield and Quality in Japonica Varieties with Different Panicle Types

Comparisons on yield and quality characters in different panicle types were studied under different N levels. The results showed that the yield increment of erect-panicle varieties was greater than that of semi-erect and curved panicle types, but the changes of yield components of three panicle types showed same trend with the increase of N application amount. Brown rice, milled rice and head milled rice all increased in three panicle types varieties, but chalkiness rate in three panicle types varied among different N applications. Compared with half-erect and curved panicle varieties, gel consistency in erect panicle varieties was shorter and the protein content was higher, which sensitive to N application also were higher.
