Abstract:
      In order to effectively utilize waxy millet germplasms, fifty-three millet strains were used for analysis on variation of agronomic and quality traits by SAS9.0 software. Main results were as follows: Variability range of agronomic traits were 5.7%~36.08%. Variability of grain weight per spike was the highest than that of the other thaits associated with variation coefficient of 36.08%, but that of mature days was the smallest with 5.7%. The plant height had significantly positive correlation with ear length, pitch numer, the numer of leaves, lenght of internode under spike, but had significantly negative correlation with grain weight. The more firm in ear firmness, the more there was short in lenght of internode under spike and ear hair length. The tested strains were divided into eight groups using class average method at euclidean distance 4.1148. Of which, the second, third and eighth groups had higher yield potential with 25 cultivars. The frequency of nonwaxy, low amylase content and waxy type were 24.5%, 60.4% and 0 respectively. The pasting temperature was 70℃~74℃ (shared 30.2%) in 15 millet strains such as in Fenggu 12, Ligu 21 and so on, associated with alkali value in 4~5. Gel consistency was above 115 cm (shared 54.7%) in 29 millet strains such as Chigu 10, Ligu 21 and so on.
