Apparently, there are no custard apple cultivars defined for the northeastern region of Brazil. The establishment of breeding programs aimed at the selection of types from productive locations for later cloning is desirable. This work's objective was to evaluate the yield (during the first three crops) and quality (first crop) of fruits from 20 half-sibling custard apple tree progenies, selected from home orchards. An additional objective was to estimate genetic parameters for the traits evaluated. A micro sprinkling-irrigated experiment was conducted in Mossoró-RN, Brazil, as random blocks with five replications. In characteristics evaluated for periods longer than a year (diameter, height and mean weight of fruits, number of fruits ha-1 and fruit yield (Kg ha-1), and a split-plot design was adopted, with progenies considered as plots and annual cropping seasons as subplots. The best progenies in terms of fruit yield (A3 and A4) are not necessarily the best for fruit dimensions and fruit mean weight (A2, FE4, JG1, SM1, SM7, and SM8). These progenies show great potential to be used in future studies on crosses or on vegetative propagation. In this regard, progeny JG2 should be highlighted as promising in terms of yield and fruit size. The progenies are not different with regard to percentages (in relation to mean fruit mass) of pericarp, endocarp, seeds, and receptacle, in the fruit, and fruit volume, number of seeds/fruit, and total soluble solids content in the fruit pulp, but progeny FE4 presents higher total titratable acidity in the fruit pulp. Narrow-sense heritability estimates were relatively high for all characteristics in which there was variability between progenies, with higher values for number of fruits ha-1 (80%) and fruit yield (78%). Relatively high coefficients of genotypic variation (around 20%) were observed for number of fruits ha-1 and fruit yield, with lower values for the characteristics. There were positive genotypic and phenotypic correlations between fruit diameter (FD) and fruit height, FD and mean fruit weight, and number of fruits ha-1 and fruit yield.

To identify superior genotypes, 42 progenies of interspecific hybrids
between American oil palm and oil palm were evaluated in an area with incidence
of bud rot. The following variables were assessed: total bunch yield
(TBY), number of bunches (NB) and mean bunch weight (MBW) from the third
to the sixth year of cultivation and estimates of genetic parameters obtained
by REML/BLUP procedures. High heritability values of the evaluated traits were
observed. The gain estimates for TBY were 14.49% for the selection of the five
best progenies and 33.36% for the selection of the five best trees, considering
multiplication by cloning. A medium correlation was observed between TBY and
NB (r2 = 0.33±0.021), a high correlation between TBY and MBW (r2 = 0.53±0.019)
and a negative high correlation between NB and MBW (r2 = ?0.60±0.018). The
results indicate a high expectation of gains with selection for TBY. |
