Blossom blight and brown rot caused by Monilinia fructicola is the most important peach disease in Brazil. Genetic resistance is a control strategy that is gaining importance in breeding programs worldwide. This study aimed to identify genotypes with higher levels of blossom blight resistance to estimate the heritability of this character; study the frequency distribution in populations; and test the possibility of maternal effect. Blossom blight susceptibility was tested in reciprocal hybridizations seedlings, as well as their parents. The detached flower technique was used in a randomized complete block design, considering each genotype as a treatment. Flower inoculation was made by spraying a M. fructicola suspension and evaluations were carried out after 72 and 120 hours using a scale of five severity levels.
The studied populations presented low phenotypic variability regarding the flower resistance/susceptibility to M. fructicola, being most of them susceptible or very susceptible. Among the tested genotypes, the cultivars Maciel and Cerrito showed less blossom blight susceptibility, transmitting this character to their progenies. Heritability estimates of the blossom blight resistance were medium to low. The low heritability and its distribution in the progenies suggest that the character has additive inheritance, without detecting deviations associated with maternal effects. |

ABSTRACT:
The objective of this experiment was to evaluate the water deficit effects on maize yield and yield components. The maize hybrid Pioneer 30F33 was submitted to five irrigation water management treatments. Irrigation management was based on crop maximum evapotranspiration (ETm). Irrigations were applied when cumulative ETm reached values of 14, 22, 30, 38 and 46 mm. The experiment was conducted on a set of 20 drainage lysimeters under a mobile rain shelter. Leaf area index and plant height were measured twice a weak in each
treatment from 29 days after emergency to harvest. Soil moisture were measure in each soil !ayer (0-20; 20-40; 40-53; 53-66 and 66-100 cm), twice a weak. Results of leaf area and plant height were similar during crop growing season for ali irrigation strátegies, and aboveground biomass accumulation at harvest was also similar for ali treatments. Maximum technical maize yield was obtained applying irrigation when cumulative ETm reached value of the 34 mm. Total irrigation depth applied was 264, 281, 278, 279, and 282 mm using the irrigation
management of 14, 22, 30, 38 e 46 mm of cumulative ETm. The use of irrigation application based on cumulative ETm values in Southern Brazil results in a easier practice to increase water use efficiency, increase maize yield and reduce application cost. |
