In order to assess the genetic control of resistance in the melon ‘Gaúcho Redondo’ to the root-knot nematode Meloidogyne incognita, an experiment was conducted in a randomized complete block design with three blocks and six treatments using the parental lines ‘Gaúcho Redondo’ (P1 resistant) and JAB 20 (P2 susceptible), as well as F1, F2, and backcross generations (RC1P1 and RC1P2). Seventy days after inoculation, individual plants were evaluated for resistance using the nematode reproduction factor (RF). The hypothesis of monogenic inheritance was rejected by the chi-square test (χ2), and results indicated that resistance is controlled by more than one gene locus, as confirmed by the quantitative analysis that revealed the presence of six genes.

“…In their study of bean plants with resistance to M. incognita race 1, FERREIRA et al (2012) also verified that the additive-dominant model was sufficient to explain the data, since the correlation obtained was also high (R 2 = 0.9881).…”

“…The panel included commercial cultivars from different breeding institutions, landraces, and parents of the following populations: ‘Bat 93’ × ‘Jalo EEP 558’ [49]; ‘Carioca’ × ‘Flor de Mayo’ [50]; and ‘CAL 143’ × ‘IAC UNA’, and also 14 F 10 recombinant inbred lines (RILs) derived from the ‘CAL 143’ × ‘IAC UNA’ cross [16]. In addition to 87 inbred lines from the IAC breeding program, the diversity panel studied herein includes 62 common bean lines from the International Center for Tropical Agriculture (CIAT), 12 from the Brazilian Agricultural Research Corporation (Embrapa), as well as nine Brazilian landraces and ten cultivars [51]. Phenotypically, this panel contains variability in ( i ) grain morphology, ( ii ) resistance to biotic factors such as pests and diseases, ( iii ) tolerance to abiotic factors such as drought, and ( iv ) the micronutrient composition of grains [51].…”

Phaseolus vulgaris is an important grain legume for human consumption. Recently, association mapping studies have been performed for the species aiming to identify loci underlying quantitative variation of traits. It is now imperative to know whether the linkage disequilibrium (LD) reflects the true association between a marker and causative loci. The aim of this study was to estimate and analyze LD on a diversity panel of common beans using ordinary r2 and r2 extensions which correct bias due to population structure (rS2), kinship (rV2), and both (rVS2). A total of 10,362 single nucleotide polymorphisms (SNPs) were identified by genotyping by sequencing (GBS), and polymorphisms were found to be widely distributed along the 11 chromosomes. In terms of r2, high values of LD (over 0.8) were identified between SNPs located at opposite chromosomal ends. Estimates for rV2 were lower than those for rS2. Results for rV2 and rVS2 were similar, suggesting that kinship may also include information on population structure. Over genetic distance, LD decayed to 0.1 at a distance of 1 Mb for rVS2. Inter-chromosomal LD was also evidenced. This study showed that LD estimates decay dramatically according to the population structure, and especially the degree of kinship. Importantly, the LD estimates reported herein may influence our ability to perform association mapping studies on P. vulgaris.

“…Nematodes are difficult to control, and crop control practices and chemical applications are often inefficient, with the latter may having serious consequences for both the ecosystems and humans (Ferreira et al 2012). The use of resistant cultivars, when available, is the most promising and viable practice for nematode control (Ferreira et al 2010).…”

The production of common bean (Phaseolus vulgaris L.) may be compromised by a variety of pests and diseases, with root-knot nematodes standing out among the soil-borne pathogens that cause significant losses. It was assessed the reaction of common bean genotypes to the reproduction of these nematodes, with emphasis on the two species most frequently found parasitizing the crop: Meloidogyne javanica and Meloidogne incognita. The experiments were conducted in a greenhouse, using a completely randomized design, with 26 treatments (genotypes), ten replications and plot consisting of a pot containing one plant. Each plot was inoculated with 1,000 eggs and second-stage juveniles and assessed at 62 days after the inoculation, when the final populations were estimated. The genotypic resistance was determined based on two criteria: reproduction factor and index. All the genotypes were susceptible to M. incognita according to both assessment criteria. The IAC Alvorada, IAC Imperador, BRS Esplendor and BRS Esteio cultivars, although may be classified as resistant to M. javanica by the reproduction factor, are classified only as moderately resistant if the assessment criterion is the reproduction index.
