Abstract: Correlation and grey correlation degree between edible qualities and agronomic traits were analyzed about the later generation hybridized of 349 lines of the RIL populations between erect and crooked panicle type. The correlation analysis results showed that the relation of gelatinization temperature （GT） and days from sowing to heading （DH） were extremely significant positive correlation and relation of GT and panicle angle （PA）, spikelet per panicle （SP）, filled spikelet per panicle （FSP）, panicle length （PL） were significant or extremely significant negative correlation. The relation of gel consistency（GC）and seed-setting rate （SS）, PL, PA, PH, 1000-grain weight（1000GW） were extremely significant positive correlation. The relation of amylose content （AC） and DH, PH, 1000GW were significant or extremely significant positive correlation. The grey correlation degree analysis indicated that SS, DH, 1000GW, PL had great effects on edible qualities, while no filled spikelet per panicle（NFS）, PA, spikelet per cm panicle（SPP） had slight effects on edible qualities.
