Association between agro-morphological traits in common bean under organic fertilization management in Brazil

The bean fly (Ophiomyia spp) is a key insect pest causing significant crop damage and yield loss in common bean (Phaseolus vulgaris L., 2n = 2x = 22). Development and deployment of agronomic superior and bean fly resistant common bean varieties aredependent on genetic variation and the identification of genes and genomic regions controlling economic traits. This study’s objective was to determine the population structure of a diverse panel of common bean genotypes and deduce associations between bean fly resistance and agronomic traits based on single nucleotide polymorphism (SNP) markers. Ninety-nine common bean genotypes were phenotyped in two seasons at two locations and genotyped with 16 565 SNP markers. The genotypes exhibited significant variation for bean fly damage severity (BDS), plant mortality rate (PMR), and pupa count (PC). Likewise, the genotypes showed significant variation for agro-morphological traits such as days to flowering (DTF), days to maturity (DTM), number of pods per plant (NPP), number of seeds per pod (NSP), and grain yield (GYD). The genotypes were delineated into two populations, which were based on the Andean and Mesoamerican gene pools. The genotypes exhibited a minimum membership coefficient of 0.60 to their respective populations. Eighty-three significant (P<0.01) markers were identified with an average linkage disequilibrium of 0.20 at 12Mb across the 11 chromosomes. Three markers were identified, each having pleiotropic effects on two traits: M100049197 (BDS and NPP), M3379537 (DTF and PC), and M13122571 (NPP and GYD). The identified markers are useful for marker-assisted selection in the breeding program to develop common bean genotypes with resistance to bean fly damage.

Agave Sisalana

The Sisal (Agave sisalana Perrine) is a crop very important for the semi-arid region of Brazil, constituting an important source of income in regions that lack options that help in their development. However, studies regarding the development of this crop are scarce, reflecting on the low technology use and ancient practices used in the production systems. Theobject of this studywas to evaluated the initial growth development of plants of Sisal (Agave sisalana Perrine) under different sources of chemical and organic fertilization and presence and absence of intercropping with common bean (Phaseolus vulgaris), in the city of Areia, Paraíba. The experiment was carried out in a randomized complete block design (RCBD), in a 2x3 factorial scheme, composed of two cultivation systems (alone or intercropped) and three fertilizationtypes (organic, chemical and no fertilization), totaling 24 treatments with four replications in an area of 25 m² each. The results showed an influence effect of the source of fertilization and the intercroppingon the initial development of the crop, and the best results obtained were with the organic fertilization and the intercropping with common bean.

Molecular Linkage Map

The development of a complete linkage map including both morphological and molecular markers is important to understand the genetic relationships among quantitatively and qualitatively inherited traits in common bean. The objective of this study was to identify RAPD markers linked to genes for four morphological traits using bulked segregant analysis and to map the markers to a molecular linkage map previously constructed in common bean. Three segregating populations were evaluated. Two BC2F2 populations with dgs (dark green savoy leaf) and blu (blue flower) induced mutant was developed with a Florida breeding line 7-1404 and 5-593 as the recurrent parent. In addition, a BC3F2 population with the y (yellow wax pod) and the arg (silvery green pod) mutants was developed from the Lamprecht line PI 527858 and 5-593 as the recurrent parent. RAPD markers linked in coupling to the morphological traits were detected to be 4.1 cM, 4.3 cM, 7.3 cM, and 12.3 cM distant from the dgs, blu, y, and arg genes, respectively. The linked RAPD markers were mapped in the molecular linkage map previously constructed using recombinant inbred population of the cross PC-50 × XAN-159. In this linkage map, we observed a linkage between the C locus and blu gene whose location was not previously known. In addition, a linkage between an abaxial leaf pubescent gene and dgs gene was observed. These results indicate that integrating morphological markers and molecular markers can result in a more complete genetic linkage map in common bean.

ABSTRACT The development of new common bean cultivars with grain characteristics that achieve greater acceptance by consumers and faster cooking time is a recent trend in bean breeding programs. This study aimed at evaluating whether different common bean lines exhibit differences in grain morphological traits and cooking time, investigating the linear relationships between these traits and cooking time, and selecting lines with superior grain commercial characteristics and faster cooking times. A randomized blocks design with three replications was used. Treatments consisted of 14 common bean genotypes grown during two seasons. Differences in the mass of 100 grains and grain length, width, thickness, shape, flatness, percentage of water uptake and cooking time were observed between lines. A high positive correlation was observed between grain thickness and cooking time (r = 0.9727). The path analysis revealed that grain thickness had the highest positive direct effect on cooking time (0.62). Therefore, fast-cooking common bean lines can be indirectly selected based on lower grain thicknesses. The DF 06-17 line presents fast-cooking grains with characteristics well accepted by the market and consumers.

A collection of 18 landraces of common bean (Phaseolus vulgarisL.) from northern Portugal was evaluated for both phaseolin pattern and a set of qualitative and quantitative traits. The phaseolin Contender and Tendergreen types were the most commonly occurring, with Boyaca and Huevo de Huanchaco present, but rare. The colour of the flower standard and wing, and seed shape, colour and size were all highly variable. On the basis of morphological traits, the landraces and testers clustered into two main groups. No relationship was found between phaseolin profile and any of the quantitative traits measured. Based on phaseolin patterns, the origin of Portuguese common bean populations was probably the Andean region of South America.

Abstract. Bareke T. 2019. Diversity and genetic potential of various morphological traits among common bean (Phaseolus vulgaris, Fabaceae) landraces. Biodiversitas 20: 3237-3245. The study was undertaken to identify the morphological diversity and genetic potential among landraces of common bean (Phaseolus vulgaris L.) at field conditions of Adama District, Ethiopia. Twenty four common bean landraces from different agroecological zones were collected and grown in three replications. Data of eight agromorphological descriptors were collected using IBPGR protocol. Accordingly, Zale wehy was significantly different (p<0.05) from all landraces with the highest mean number of pods per plant. On the other hand, the mean number of seeds per pod was significantly (p<0.05) higher for Dobole followed by Dima, Kalibushay and Adi tikko while Logoma dume has the lowest number of seeds per pod. The average number of seeds per pod had inverse relationship with seed size. The highest diversity was found in number of seed per plant among landraces while the lowest diversity was found in number of seed per pod. Based on morphological traits similarities among 24 landraces were classified into 4 major categories. Heritability was the highest for seed length (0.97) followed by number of seed per pod (0.94) and seed per plants (0.69) and the lowest (0.1) for height of plant and the rest found between these values. The variability observed in seed length, number of seeds per pod, number of seeds per plant and number of pods per plant which could be utilized in variety improvement programs. Therefore, crop breeders could give emphasis to these traits of landraces to monitor and use for the breeding program, future production and for other domestic purposes.

Seed Characteristics

This work investigated the genetic control of seed morphological traits and its correlations with grain yield in common bean. Three crossings among bean cultivars with different growth habit and seed characteristics were analyzed. F1 progenies gave origin to F2, RC1P1F1 and RC1P2F1 generations. Random samples of seeds from F2 generations and parents, F1 and backcrossings were sown during the season 2003/2004. Plant grain yield and seed morphological traits were determined by a sample of 150 plants from F2 generations and 20 plants from parents, F1 and backcrosssings. Genetic effects involved in each crossing were obtained from estimates of genetic components means and genetic and environmental components of phenotypical variance. Results showed that the seed morphological traits were controlled by a complex of genes, with additive effects predominance although dominance effects were present. High and negative correlations among seed length and thickness with grain yield suggested greater grain yield in bean plants with smaller seeds.
