Abstract:

In this study, the sweet resin Foeniculum vulgare Mill. It is intended to determine the relationships between the yield and some yield items. Twenty lines of resin were used as material. The highest positive ratio r = 0.915 is determined between biological productivity and single plant productivity. The impact of the plant length, branch number, number of shadows and number of shadows on the single plant yield has been positive. The weight of a thousand seeds has been found to be linked in a negative direction to the rate of flying oil. The maximum to the seed yield - the negative effect to the biological yield, while the highest positive and direct effect has been shown by the number of shadows. In addition, the single plant production, the length of the plant and the weight of a thousand seeds have positively affected the seed production. The direct effect of single plant productivity on the flight oil ratio is 32%. 95 was the highest, followed by 24.60% of plant length and 15.11% of branch numbers. As a result, the single plant yield, the number of shadows and the flowing fat ratio of the plant-long sweet resin and the seed yield can be recommended as phenotypic selection criteria for improving the yield.
