Abstract：To study the characteristic differences between Zhongyan 100 and NC89 and their genetic characteristics,reciprocal crosses were formulated with two parents and the plot trial was arranged.The agronomic traits,economic traits,natural disease characteristics,chemical composition,aroma components and sensory quality were analyzed.The results showed that the field performance of Zhongyan 100 was better than that of NC89,but the internal quality of NC89 was better.F1 generation showed mid-parent heterosis or heterobeltiosis in agronomic traits,economic traits,and disease resistance.There were differences in the performance of reciprocal crosses.The yield and output value of hybrid (NC89 × Zhongyan 100)F1 were significantly higher than those of two parents,and the sensory quality of F1 showed significant heterosis.The resistance of hybrid (Zhongyan 100 × NC89 ) F1 was better than parents,and the potassium content of F1 showed significant heterosis.The total amount of aroma components of NC89 was significantly higher than that of Zhongyan 100,and the hybrid (NC89 × Zhongyan 100)F1 was higher than Zhongyan 100 but lower than NC89.
