INFLUENCE OF MORPHOLOGICAL AND PHYSIOLOGICAL CHARACTERISTICS OF LENTIL (LENS CULINARIS MEDIK) SAMPLES ON YIELD COMPONENTS AND CORRELATION ANALYSES OF SOME CHARACTERISTICS

The aim of the research is to study the correlation between crop capacity and physiological characteristics of Lentil (Lens culinaris Medik). Determination of correlation between physiological characteristics and crop indicators, and assessment of their influence on grain yield give an opportunity to select genotypes with high crop capacity. According to the results of the analysis, strong positive correlation was detected among the valuable economic characters of lentil genotypes, i.e. between indexes such as number of grains per plant with grain weight per plant r=0.88*** and grain productivity per plant r=0.71***; between grain weight per plant and grain productivity in 1m2 plot r=0.79***; among chlorophyll ‘a’, chlorophyll ‘b’ and carotenoid content in leaves (r=0.92***, r=0.81*** respectively); between net photosynthetic productivity and biomass in 1m2 plot (r=**0.67;). Moreover, moderate positive correlation was detected among the indicators of grain number per plant (r=*0.54) and grain weight (r=**0.57) and grain productivity (r=*0.62). Among the lentil genotypes, K-72015 genotype, which has a good result based on the analysis of morphological-physiological and productivity characteristics, gives the opportunity to grow it as a new promising variety in the republic and obtain a higher yield.
