STUDY OF DEPENDENCE OF PRODUCTIVITY IN BEAN GENOTYPES ON STRUCTURAL ELEMENTS

The role of beans in meeting population’s need for proteins in a cheap and efficient way is incomparable. Proteins, thanks to rich amino acids, vitamins and minerals that they contain, make beans a quality food. In order to fulfill population's demand of beans provided solely by domestic production it is necessary to create new and fruitful varieties. Scientific researches and studies of potential capacities of introduced as well as already known sorts can be helpful in archiving this goal. All in all, collection, study and reproduction of beans, known as an alternative healthy and efficient supplier of daily amount of proteins necessary for human body, require creation of new varieties. In Azerbaijan, the sowing of vegetable have been does not have much production value. The culture is mainly used for research purposes and is cultivated in small areas, like garden. Therefore, the study of the morphobiological features of plants of the prospective variety in each region and the comprehensive study of the genetic resources of culture is relevant. The article provides an assessment of the structural elements of bean varieties collected and introduced from different regions of the country, which are of great importance in productivity. The samples with complex agrobiological indicators have been identified. A comprehensive study of potential productivity of bean accessions allow their use in the selection such as primary material, sources and donors of household-valuable features. In our study, biometric analysis of plants in the collection showed that productivity is mainly determined by the variability of key traits, genotypic diversity and the state of the year of cultivation. Among the traits, the number of grains and beans in the plant, the coefficient of variation of the grain mass in the plant is a strong indicator of variability with moderate significance. The number of grains in beans, the variability in the mass of 1000 grains is characterized by moderate levels. A strong positive correlation were recordedbetween the number of grains in beans and the number of grains in plants; weight of 1000 grains and number of grains per plant; mass of 1000 grains and number of grains per bean, number of beans per plant; it was also found that there was a very weak relationship between the mass of the seed and the length of the stem.
