| Maize(Zea Mays L.)was one of the grain crops that most widely distributed in the world.. To improve maize yield and quality, the key was to cultivate new varieties, breeding efficiency, however, can not do without the use of founder parents. Mo17 was an important component of founder inbred lines and produced lots of inbred line. Comparison with traditional method, GGEbiplot showed all information in the datatable by picture and supply more explain. Greatly improved the understanding of data.. In this paper,2008,2009, respectively, grown in Heilongjiang, Shandong, Sichuan and Mo17 inbred lines were derived from analysis of GGE biplot. combined with trait under different environments. For these materials to the regional stability and adaptability to evaluation, the main agronomic characters, and reveal the relationship between different planting area of main component factor. Main result was as follows:1. In the different year, the agronomic characters variance of Mo17 and its derive lines in Heilongjiang is bigger than Sichuan; In the different place, EH/PH, total leaf number, ear rows, ear diameter, axis diameter in Heilongjiang were greater than another places. plant height, ear position, stem diameter, tassel branch, leaf orientation value, Percentage of plants with two ears on same plant in Shandong were greater; tassel length, Percentage of bare plants, ear tip length, row grains in Sichuan were greater.2. In the 18 Experimental materials, the trait of 210,209,315,101,102 in the different place and year is greater than else.3. The trait of total leaf number, ear diameter, tassel branch, axis diameter, ear rows, grain length, stem diameter of inbred line 316 in Heilongjiang was best, next was 212>101>106 >213>317>211;The trait of plant height, ear position, row grains, grain yield per ear, tassel length,100 grain weight, EH/PH of inbred line 210 in Shandong was best, next was 102>104 >209>103>101;The trait of ear position, grain yield per ear, row grains, tassel length, EH/PH, grain length plant height, total leaf number,100 grain weight, stem diameter of inbred line 101 in Sichuan was best, next was 210> 104>209>317.4. In all environments of different Geno-Trait biplot comparison, Strong relevance were a). ear position, plant height,100-grain weight, EH/PH, grain length, grain yield per ear, tassel length, row grains;b). ear diameter, tassel branch, total leaf number, leaf orientation value, ear rows, Percentage of plants with two ears on same plant, stem diameter; c). axis diameter, barren ear tip length.5. In all environments, the relation of trait were that a). plant height, ear position, EH/PH, stem diameter, leaf orientation value, total leaf number was a positive correlation; b). ear diameter, ear rows, axis diameter, barren ear tip length was a positive correlation; c). tassel branch, tassel length was a negative correlation; d). Percentage of plants with two ears on same plant, Percentage of bare plants was a negative correlation.6. Principal component analysis to the cumulative contribution rate to 59.3% of all the characters are divided into 3 principal components:Ear Factor, PlantType Factor,Yield Factor. And their contribution rate was 28.4%,20.9% and 10.0%. Ear Factor contains the traits:plant height, ear position, tassel length, barren ear tip length, ear rows, row grains,100-grain weight, grain yield per ear and axis diameter; PlantType Factor contains the traits:plant height, ear position, tassel branch, leaf orientation value, total leaf number, ear diameter; Yield Factor contains the traits:plant height, EH/PH,100-grain weight, total leaf number, grain yield per ear, ear diameter, Percentage of plants with two ears on same plant, Percentage of bare plants... |
