“…Now the university has created a significant genetic collection and a hybrid fund of dwarf clonal apple rootstocks, which annually contribute in comprehensive comparative studies [1][2][3][13][14][15][16]. The identified stocks are characterized by the presence of anthocyanins in the tissues and increased resistance to adverse climatic conditions, especially to the damaging temperatures of the winter period [17,18].…”

This paper reveals main patterns of development of advanced clonal apple rootstocks of the Michurinsk State Agrarian University selection in the mother plantation. The studied growth and development indicators of shoots, as well as the level of their rooting in 40 genotypes, demonstrate significant heterogeneity of hybrid plants, which is due to their different genetic origin and the associated unequal growth force of parent shrubs. Correlations between the main quantitative morphological characters of parent shrubs of the studied genotypes were revealed. An interrelation of the height of the parent shrub and the area of its leaf surface is noted - on the expectation of 0.71 shoot; for the entire uterine shrub – of 0.45; between the output of standard layering from the shrub and the average rooting score (at 0.72). Promising clonal rootstocks with high yield indices in the mother plantation have been identified.

This study presents a new mathematical model of the physiology of the plant open system development in the conditions far from equilibrium. Unlike existing approaches, our model is based on the equations describing competition for the substrate between the three main compartments of cultivated plants - the root, stem and leaf system in extreme conditions. Exchange with the external environment occurs through two channels - through the leaves and the root system. The internal control channel is defined as a function of limiting the plant biomass through the biomass of the individual structural parts. The model viability was tested on the example of physiological model of tomato development. The system’s behavior was studied under two varieties of extreme conditions - a lack of nutrients in the soil and a low level or lack of solar radiation. In the first case, the model shows the restructuring of the system after several levels of vibrations to a stable state with a low consumption of substrate and a redistribution of the leaves, stem and root masses. In the second case, the calculations show a significant suppression of leaf cover biomass and mass redistribution in favor of the stem and root. However, even in this case, after a period of instability, the system comes to a stable state with the mass of the stem exceeding the mass of other structures. For each case, phase trajectories of the biomass and substrates behavior are constructed.

The paper shows the results of many years of experience in breeding low-growing clonal apple rootstocks at Michurinsky State Agrarian University. The relevance of the introduction of digital technologies at all stages of the breeding process from the formation of a data bank for the selection of parental pairs to research in the garden of the competitive study of rootstock-varietal combinations is shown. The apparatus and software for specific research stages are proposed. It is found that the developed methodology and digital technologies make it possible to significantly reduce the time of the breeding process, achieve the intended results faster and more efficiently and most fully reveal the genetic potential of breeding achievements.
