以吉林省1986～2011年育成的23个绿豆品种为试验材料,研究了绿豆产量及与产量相关农艺性状的变化。结果表明,吉林省绿豆产量在1986～2011年间的品种改良过程中提高了22.99%,单株荚数、单荚粒数和单株产量都显著增加,说明随着育成年代的推进,新育成绿豆品种的库容在扩大。单株荚数、单荚粒数、单株产量、荚长与产量呈显著正相关,其中单株荚数与产量呈极显著正相关,表明单株荚数是决定产量的主要因素。叶片长与叶片宽随育成年代的推移变化不显著,但叶片宽与产量呈显著正相关。株高、主茎节数和分枝数随育成年代的推移而显著降低,其中主茎节数呈极显著相关,且株高和主茎节数与产量呈显著负相关,分枝数与产量呈不显著正相关。表明吉林省绿豆高产育种目标应放在增“源”扩“库”上,在适当增加百粒重的基础上,选择荚多、荚长的新品种。
In this paper, 23 mung bean cultivars bred from 1986 to 2011 in Jilin Province were used as experimental materials to study the changes of yield and related agronomic traits of mung bean. The results showed that the yield of mung bean in Jilin Province increased by 22.99% from 1986 to 2011, and the number of pods per plant, the number of pods per plant and the yield per plant increased significantly, indicating that with the advancing age, Variety of storage capacity is expanding. The number of pods per plant, the number of pods per plant, the yield per plant and the length of pods were significantly and positively correlated with the yield. The number of pods per plant was significantly and positively correlated with the yield, indicating that the number of pods per plant was the main factor determining the yield. Leaf length and leaf width did not change significantly with age, but leaf width and yield were significantly and positively correlated. The plant height, the number of main stems and the number of branches significantly decreased with the passage of breeding age. The number of main stems was significantly and significantly correlated, and the number of plant height and main stems was negatively correlated with the yield. The number of branches and yield There was no significant positive correlation. The results showed that the goal of high yielding mungbean breeding in Jilin should be put on the “source” and “extension” library. Based on the increase of 100 grain weight, new varieties of pods with longer pods were selected.
