摘　　要：为探究不同番茄品系间产种量及种子质量的差异,选择‘CHSLTW’‘ZHS’‘ZHSFB’‘DTXZ’‘JSWZ’等5个小果型番茄品系,测定了产种量、单果质量及种子质量,并对单果质量、产种量、种子千粒质量、发芽势和发芽率之间的相关性进行了分析。结果表明:‘ZHSFB’产种量最高,‘ZHS’‘CHSLTW’和‘JSWZ’等3个番茄品系种子的发芽势和发芽率较高,其中‘ZHS’的单果质量和千粒质量最高。单果质量与千粒质量存在显著正相关;发芽势与产种量为显著负相关;千粒质量与发芽势和发芽率存在显著性正相关。番茄品系间产种量和种子质量存在差异,产种量和种子质量也存在一定的相关性。The seed yield and seed quality of 5 different tomato strains were studied with‘CHSLTW’‘ZHS’‘ZHSFB’‘DTXZ’and‘JSWZ’as experimental materials.The seed yield,single fruit weight and seed quality were studied,and the correlation among single fruit weight,seed yield,1000-seed weight,germination potential and germination rate were analyzed.The results showed that the seed yield of‘ZHSFB’was the highest,the germination potential and germination rate of‘ZHS’‘CHSLTW’and‘JSWZ’were higher,among which the single fruit weight and 1000-seed weight of‘ZHS’were the highest.There was a significant positive correlation between the single fruit weight and 1000-seed weight.Germination potential was negatively correlated with seed yield.There was a significant positive correlation between seed weight and germination potential and germination rate,and there were difference and correlation between seed yield and seed quality of different tomato strains.
