THE EFFECT OF DIFFERENT TYPE OF CYTOPLASM ON SEED FRACTIONS IN MAIZE INBRED LINES
Published: 12 Sep 2020
Abstract: The seed in order to meet requirements of cropping practices and growing systems in the production of commercial maize. The aim of the present study was to determine the effects of The seed processing technology depends on the seed fraction. The introduction of new and improved solutions in maize seed processing contributes to the improvement of traits of different types of cytoplasm (cms-C, cms-S and fertile), and environmental factors on the medium large flat seeds of maize inbred lines. The study encompassed the 12 same maize inbred lines of each type of cytoplasm. The trial was set up according to the complete randomised block design in two locations with three replications. Statistical-biometrical data processing was based on means per replication and encompassed the analysis of variance. On the basis of this analysis, it was determined that there were significant differences among inbred lines regarding the medium large flat seed fraction (MLF) in dependence on the type of cytoplasm, year and the location. The average values of the seed fraction varied over inbreds from 0.4% to 16.3%. The highest, i.e. lowest value for this trait was expressed by sterile cytoplasm cms-C, i.e. fertile cytoplasm, respectively. Furthermore, a greater share of MLF seeds was recorded in the first year and the first location than in the second year and the second location. The inbred line × location interaction points out to very significant (Lsd0.001) differences in the content of MLF seeds of maize inbred lines in dependence of observed locations. The years of investigation and locations significantly (Lsd0.005) affected the content of MLF seeds in maize inbred lines. The analysis of obtained results points out to a significant effect of the type of cytoplasm on the medium large flat seed fraction.
