摘要
对16个番茄品种的13个农艺性状进行相关分析的结果表明,平均单株产量和总采果数、株高、叶片数的相关性达显著水平,相关系数分别为0.536 8、0.614 4和0.518 2。农艺性状对产量的通径分析结果表明,早期采果数、平均单果重、果肉厚、株高、总采果数对平均单株产量直接作用较大,早期采果数通过总采果数、第1穗果数、平均单果重、株高、第1穗节位茎粗、果肉厚对平均单株产量间接作用均为负值。
A correlation analysis was made among 13 agronomic characters to 16 varieties of tomato. The results showed that the correlation among reach significant level of yield per plant with total fruit number ,plant height ,the number of leaf, the correlation coefficients were 0. 536 8,0. 614 4 and 0. 518 2, respectively. The path analysis was made of Agronomic characters to the output, the results also showed that early total fruit number,the average fruit weight,thick of flesh,plant height,total fruit number were larger directly effected to yield per plant, and through total fruit number,the first spike fruit number,the average fruit weight,plant height, the first spike ganglion position, the stem diameter,thick of flesh and early fruit number indirectly effects were negative to yield per plant.
