Seven baby corn inbreds were crossed in a complete diallel scherne. The sinble-cross hybrids obtained were assessed at the São Manuel Experimental Station, in São Paulo State, Brazil. The experiment was set up in a randomized complete block design with three replications, including one commercial control. The experimental plots consisted of a single row, 5 m long, with 25 plants. The traits assessed were: number of ears/plot, weight, lengh and diameter of husked and dehusked ears, plant height and ear height. General and specific combining ability effects (GCA and SCA) were determined. There was genetic variability among hybrids and the best hybrid (27Ax31B) was superior to the control for number of ears plot and weight of ears dehusked. Inbreds 27 and 29 showed the best GCA effects for number of ears/plot, weight of husked and dehusked ears. The magnitude of GCA showed that the additive effects were dominant in most traits evaluated. The existence of dominance effects was also found.

The nutritional management of the coffee clonal garden influences the production and physiological quality and seedlings production of vegetative propagules. Thus, this study aimed to analyze the seedlings? production from clonal cuttings taken from Coffea canephora mother plants grown with increasing nitrogen mineral doses. The cuttings were taken from C. canephora var. botany Robusta, from the Embrapa Genetic Improvement Program of Rondônia. The mother plants received nitrogen fertilizer at different doses: 0 (Control); 50; 100; 150; 200; 250 and 300 kg of N per hectare divided into 4 applications, during 150 days of orthotropic stems growth (shoots). The following parameters were evaluated: Dry mass of cuttings, nutritional content of cuttings, and seedlings production, with growth analysis at 0, 48, 61, 80, 101, 122, 143, and 164 days after staking (DAS) and analysis of vegetative characteristics at 122 DAS. The nitrogen fertilization in the mother plant resulted in the variation of macronutrient accumulation in cuttings, but the order K> N> Ca> P> Mg> S was maintained, regardless of N dose. In addition, a positive correlation between nitrogen doses and dry matter accumulation, as well as the physiological quality of seedlings was identified. |
