| Title : | EFFECTS OF DIFFERENT TYPES OF CYTOPLASM ON THE KERNEL ROW NUMBER OF MAIZE INBRED LINES |
| 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 kernel row number of 12 maize inbreds lines. The trial with inbred lines was set up in two locations (Zemun Polje-Selection field and Zemun Polje-Školsko dobro) in 2013 and 2014. Moreover, the three-replicate 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 included the analysis of variance. According to this analysis, significant differences in the kernel row number were established among inbred lines in dependence on the type of cytoplasm, year and the location. The average kernel row number ranged from 10.3 (L9) to 15.8 (L5 and L7). The variation of the kernel row number, related to the source of cytoplasm, was very significant. Differences (Lsd0.01) in the kernel row number were not determined in inbred lines L5, L8, L10 and L12 in regard to the type of cytoplasm: cms-C, cms-S and fertile. The average kernel row number significantly (P1%) varied in regard to the year of investigation. A higher average value (13.75) was established in 2014 than in 2013 (13.31). The kernel row number per year very significantly varied (Lsd0.01) in all inbreds, but the differences were not significant in the inbreds L2, L3, L8, L9 and L12. Gained results point out to effects of different types of cytoplasm on the kernel row number. |
