In this experiment, Nongda 8, Nongda other 10 21 millet varieties for the study materials, completely randomized design, by the number of births of days, morphological and measured factors and yield of nutritional quality, amino acid content, chlorophyll fluorescence characteristics, yield components The main results are as follows:1 Relationship between Growth and YieldYield and heading, grain filling, maturity, booting was a significant positive correlation with the growth period, jointing positive correlation was significantly negatively correlated with seedling and seedling; 8 Growth of direct communication on Yield path coefficient:heading> filling> booting stage> ripening> growth period> jointing stage> seedling> seedling and heading respectively seedling, seedling, jointing, booting, maturity yield the interaction effect is greater than the main effect of various other growth period.2 Relationship between morphological indexes and yieldYield and ear length was significantly positively correlated with ear diameter was significantly positively correlated positively with plant height, leaf area was, and stem diameter were negatively correlated; five morphological indicators yield direct path coefficient is:ear length> ear diameter> leaf area> stem diameter> plant height and ear length and ear diameter, respectively, leaf area, plant height, stem diameter interaction effect on yield is greater than any other form of indicators main effects.3 Relationship nutritional quality and yieldProduction and carbohydrate was significantly and positively correlated positively with the protein was, and ash, fat, fiber negatively correlated; 6 nutritional quality of yield direct path coefficient: Carbohydrates> Protein> ash> fiber> fat and protein and carbohydrates, respectively, ash, fat and other nutrients fiber quality indices for the main effect is greater than the yield of the interaction effects.4 Relationship between amino acid and yieldYield and tryptophan, valine, leucine, isoleucine, methionine, threonine was positively correlated with phenylalanine, lysine negative correlation. The relative importance of each amino acid to yield indexes were:tryptophan> valine> Methionine> Lysine> isoleucine> Phenylalanine> leucine> threonine, and tryptophan acid and lysine, respectively, valine, methionine, isoleucine, phenylalanine, leucine, threonine yield interaction effect is larger than the main effect of each amino acid other indicators.5 Relationship chlorophyll fluorescence characteristics and yieldYield and Chlorophyll b was positively correlated, negatively correlated with chlorophyll a, chlorophyll a/b, chlorophyll a+b. Yield and F0, FM was positively correlated with the FV/FM was negatively correlated. Chlorophyll fluorescence respectively direct path coefficient at a yield of: chlorophyll b> chlorophyll a/b> chlorophyll a+b> chlorophyll a, F0> FM> FV/FM.6 Relationship between yield components and yieldYield and panicle was significantly positive correlation; and grain number was a significant positive correlation was positively correlated with grain weight; the relative importance of yield components on yield were:panicle> grain number> grain weight. Grains per spike and spike, respectively, grain weight on yield interaction effect is greater than the main effects of grain number and grain weight.
