Based on physiological differences between male and female plants of the valuable green leafy vegetable, dioecious sorrel, an instrumental method for detecting sex in this species is proposed. Biennial sorrel plants in the transition to the generative stage of development were used to selectively select potential parental pairs for subsequent crossing. Differences in the morphology and physiology of photosynthesis between male and female genotypes, expressed in different ratios of chlorophyll, carotenoids, and fluorescence intensity indices associated with the functioning of photosystem II, were found to indirectly affect the spectral reflectance characteristics of the leaf surface. A screening of the most common indices used in hyperspectral data analysis revealed that sex detection can be performed using both NDVI and (preferably) SIPI and MTCI indices. The simplest method is analysis of the lower (abaxial) leaf surface. Thus, analysis of hyperspectral characteristics of leaf reflectance allows for reliable sex identification of sorrel plants at the budding stage.
