lsozyme biochemical marker may be useful tool for genomic analysis of maize populations undergoing recurrent selection. Thus, isozymes markers was utillzed for assess tbe changes in tbe genetic variability and distance in a BraziUan composite population of popcorn following four cyeles of recurrent selection for yield. Qne hundred and ninety-six half-sib families were evaluated from each cyele and tbe ten highest-yielding families (5.2%) were recombined to produce the next cyele. lsozyme analysis considered 80 seedlings per cyele. Simple linear regression equations were estimated among tbe allele frequencies in each locus in function of tbe selection cyeles, the genetic distances among the cyeles and tbe average heterozygosity per locus for each cyele. Regression analysis did not reveal any common trend for changes in aUele frequencies presumably due to selection. The estimates of tbe number of polymorphic locus, of tbe mean of aUele per locus and tbe mean heterozygosity did not reveal any reduction in variability. lt was concluded tbat four selection cyeles did not cause relevant changes in tbe variability or genetic distance among the selection cyeles of CMS-43 popcorn population. lsozymes markers analysis showed that tbe number of recombined half-sib families in recurrent selection was suitable. |

Clearfield® technology is an important tool for chemical weed management in rice fields, however, carryover of these herbicides is still a concern for crops in succession. In this study, we aimed to evaluate the impact of the herbicide Kifix® (imazapic + imazapyr) associated with Clearfield® technology of rice crops on ryegrass in succession, as well as on non-Clearfield® rice and soybean grown in rotation, in addition to the control potential of jointvetch (Aeschynomene rudis and A. denticulata) from 2016 to 2018. The experiments comprised the application of Kifix® to Clearfield® rice grown in the first experimental year, evaluating its impact (1st summer) on ryegrass grown the following winter, as well as on soybean, rice and non-Clearfield® rice grown the following summer (2nd summer). The results reported reductions in jointvetch density and infestation as Kifix® doses increased; as well as mild damage from Kifix® residues on ryegrass sown in succession to Clearfield® rice, as well as on non-Clearfield® rice and soybean in rotation to Clearfield® rice. In addition, the possibility of residue accumulation of Kifix® in the soil after repeated applications should be verified in further studies. |
