Morphobiological features of collection samples of peppermint (Mentha piperita L.) in the conditions of the forest-steppe of Ukraine

Biotypes 263/23, 266/23, 268/23, 269/23 were significantly inferior to it, samples 270/23, 271/23 and 272/23 were at the standard level.The F 5 274/23 hybrid population significantly exceeded the standard in 2022.The productivity of one plant of the analyzed populations was on average 1.91-2.62g, which differed from the data of the standard by (-0.12) -0.59 g.In biotypes 270/23, 271/23, 272/23, 273/23, 274/23 and 275/23, this indicator was not inferior to the standard.A weak positive correlation was noted between plant height and spike length; weak negativebetween the productivity of one plant and plant height and spike length; averagebetween the mass of 1000 grains and the productivity of one plant; average negativebetween the number of ears in an ear and the height of the plants and the length of the ear; a strong positive relationship was observed between the number of spikelets in a spike and the productivity of one plant.
