Abstract

The aim of the present study was to determine effects of both, different types of cytoplasm (cms-C, cms-S and fertile) and environmental factors on the number of kernels per row. Twelve maize inbred lines were tested in two locations in Zemun Polje (Selection field and Školsko dobro) in 2013 and 2014. The three-replicate comparative trials were set up according to the randomised complete block design within each type of cytoplasm. Each plot within the replicate consisted of four rows. Fertile versions of inbred lines were sown in two border rows and they were pollinators for their sterile counterparts. Statistic-biometric data processing was based on mean values per replicate and encompassed the analysis of variance. Gained results showed significant differences in the number of kernels per row among inbred lines in dependence on the type of cytoplasm, year and the location. The average number of kernels per row ranged from 15.6 (L6) to 25.9 (L9). Depending on the type of cytoplasm, the higher average number of kernels per row was detected in cms-C cytoplasm (20.4), than in fertile cytoplasm (20.0) and cms-S cytoplasm (19.8). In both years of investigation, the variation of average values of the number of kernels per row was very lines in 2014 (21.30) was significantly higher than the one recorded in 2013 (18.83). Comparing observed locations, a higher average number of kernels per row was determined in the location Zemun Polje-Selection field (20.58) than in th
