Summary: This study aimed to characterize the genetic diversity of daylily species, early hybrids, and cultivars using SSR markers and identify the origin of early hybrids. Samples from different types of daylilies were collected, and SSR primers developed for Citrus x citrofortunella were used. The most informative primer was SAU00097. Heterozygosity was highest in Lithuanian cultivars and lowest in species. Genetic relationships showed that fulvous daylilies formed a separate cluster. The highest variation among genotypes was observed in the species group, while modern cultivars had the least variation. The putative origin of early hybrids was analyzed, and triploid species were identified as ancestors of several modern cultivars.

Summary: This report presents the complete genome sequence of a Passiflora chlorosis virus (PaCV) isolate found in passion fruit plants in Israel. The genome sequence analysis reveals that PaCV is a distinct species with high similarity to bean common mosaic necrosis virus (BCMNV), a closely related virus. Using quantitative PCR, the virus was detected in symptomatic leaves, particularly in chlorotic leaves, but not in healthy leaves.

Summary: The study found moderate genetic variability among Brazilian Jatropha breeding populations, confirming the initial hypothesis. It is recommended to use a greater number of individuals per family rather than the number of families in breeding programs to exploit the greater variability within populations and obtain higher gains with selection.

Summary: Genetic diversity was analyzed in two wild populations and three families of Scylla species, indicating high genetic diversity in the wild paternal S. paramamosain population and suggesting its suitability for artificial breeding. Analysis of molecular variance showed that genetic differentiation mainly occurred within populations, indicating potential genetic differentiation among Scylla family groups due to artificial breeding. The F-1 hybrid offspring showed close genetic relationship and potential for artificial breeding with the paternal S. paramamosain population.

Summary: This study revealed an increase in flavonoid, anthocyanin, and proanthocyanin content in the fruit peel with maturity, with higher levels observed in purple passion fruit compared to yellow passion fruit. Enzymes and genes such as C4H, 4CL, UFGT, GST, PePAL4, Pe4CL2,3, PeCHS2, and PeGST7 were identified as potentially important regulators of flavonoid metabolism in passion fruit peel.

Summary: This study identified genomic regions associated with cassava starch paste properties (CSPP) and found several SNPs with significant associations. The results showed that CSPP is genetically controlled, especially on chromosome 18, and suggested potential candidate genes on chromosomes 17 and 18 for the regulation of CSPP. These findings have implications for breeding programs aiming to improve cassava root quality and select high-value starches.

Summary: The study on cassava breeding analyzed various factors affecting flower abortion and proposed strategies to overcome them, providing new insights and methods for efficient breeding. Through experiments and analysis, reproductive barriers and pollen-pistil interactions were studied, leading to the identification of population structure of elite parental clones. Significant parental effects were identified, indicating the existence of reproductive barriers among certain cassava clones, and non-additive genetic effects played a role in trait inheritance. Pollen viability and pollen-stigma interactions were found to be significant for successful fertilization, with variations in pollen viability and stigma receptivity depending on clone and flowering stage.

Summary: This study evaluated cassava genotypes for resistance to root rot disease in a field with a previous high disease incidence and identified possible genomic regions associated with field resistance. The severity of root rot was correlated with genotype survival, plant height, shoot yield, and fresh root yield. The genotypes were classified into five clusters based on resistance level, and the top 10 performing genotypes were selected as potential parents for breeding resistant progenies.
