Several genetic regions having major effects on maturity have been identified using RFLP analysis. One such region on chromosomes 8 is important across several diverse genotypes and ccounts for up to 50% of the variation for maturity in a cross involving an inbred line (N28) and a 20-backcross generation derivative (N28E). In addition to the chromsome 8 QTL for maturity, we have evidence using the backcross-derived line approach for regions controlling maturity on chromosomes 1, 2, 3, 5, 7, and 9. Chromosome 5 appears to be especially important in both magnitude of effect and across several genetic hackground. Maturity as measured by days to pollen shed or silking may be controlled by additive or nearly dominant gene action depending on the chromosome region. The marker-trait linkages were consistent across environnments based on A662 X B73 F3 per se and testcross evaluations from three locations in one year. UMC12 (chromosome 8) and UMC54 (chromosome 5) also marked important regions for maturity in these materials. |

Abstract: The current scenario of Agroforestry Systems (AFS) worldwide lacks specific machinery, resulting in practically all operations being carried out manually. This leads to a significant physical effort for small-scale farmers and limits the implementation of AFS to small areas. The objective of the study was to evaluate the suitability of existing machines for performing agroforestry tasks. This research utilizes Descriptive Statistics and Exponentially Weighted Moving Average methods to evaluate the data and compare the treatments, where different machines are used to cut Mombaça grass (Megathyrsus maximus Jacq): (i) costal brushcutter (CBC); (ii) tractor-mounted rotary brushcutter (RBC); and (iii) mini grain reaper machine (GRM). The experiments were conducted in Jaguariúna, São Paulo, Brazil. GRM is recommended for achieving greater biomass production, reducing raking time, and minimizing operational costs. CBC is suitable for smaller areas due to its affordability and slow operation, which requires significant physical effort. RBC is recommended for reducing working time, physical effort, and personnel costs, making it suitable for larger-scale contexts. |
