The objective of this work was to evaluate the germination of 12 rice genotypes under propionic acid stress, a phytotoxic compound produced in low drainage soils with high organic matter content. The tests were conducted with the first count of germination (PCG) and germination (G) of the genotypes subjective to 0, 3, 6, and 9 mM propionic acid concentrations. The seeds of each genotype were placed in germitest paper pre-soaked in treatment solutions forming individual bags. The germination was performed at 25∘C and the counts were carried out at 7 (PCG) and 14 days (G). A factorial random block design was performed with four replications of 50 seeds per genotype. Our study revealed that doses up to 9 mM propionic acid in the pre-soaking solution were efficient for genetic variability studies involving the character germination in rice; genetic variability for germination was detected in the collection of rice genotypes when subjected to propionic acid toxic effects. The genotypes Guichow, Dawn, and Toride-1 showed germination stability when subjected to increasing levels of propionic acid, and genotypes originated from irrigated system-cultivation performed better when subjected to propionic acid stress. These three genotypes will be a good biological material to for enhance the resistance to phytotoxic compounds in rice. |

A first integrated linkage map of Accasellowiana (Berg.) Burret (2n=2x= 22), commonly known as ‘pineapple guava’ was constructed using a 160 (TCO×BR) full-sib F1 progeny based on intersimple sequence repeat (ISSR), amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers. To develop an integrated map, we used a novel statistical approach that provided a simultaneous estimation of linkage and linkage phases based on maximum-likelihood analysis. The integrated map comprised 219 (27 ISSRs and 192 AFLPs) linked markers that were assigned to 10 major linkage groups (LG) representing a total map length of 2875 cM and average distance between markers of 13.8 cM. TCO (14 LG, 83 markers, 1264.6 cM) and BR (18 LG, 94 markers, 1295.1 cM) parent maps were also constructed through the same statistical approach but using only appropriate pseudo-testcross configuration markers. All the LG of the integrated map shared markers with either TCO or, BR or both parental maps. The integrated map provides a framework for further genetic and genomic analyses in A. sellowiana. |
