This study was conducted to identify suitable parental genotypes for breeding for resistance to bruchid and to identify the farmers’ preferred traits in common bean. For this study, 144 diverse common bean genotypes were planted in an alpha lattice design, with 3 replications at 3 locations. Participatory variety selection was done using 20 farmers at each location. Farmers identified a number of criteria for selecting suitable varieties. Yield and yield-related traits were ranked as the most important selection criteria by all farmers at all locations. However, women ranked culinary traits as the top criteria, while men were more interested in marketable traits. From the 144 genotypes, farmers selected the 10 best genotypes in all the locations. The majority of the genotypes selected at Melkassa and Alemetena were small white-seeded released varieties and breeding lines. However, all the genotypes selected at Arsi Negele were predominantly landraces of small red-seeded beans. Traits such as earliness and resistance to storage insect were important in Melkassa and Alme tena but received less attention in Arsi Negele. The integration of the farmers’ selection preferences with the breeders’ criteria can improve the efficiency of plant breeding by developing crop varieties that better fit the specific needs of the farmers.

Lattice Design

The present study was conducted on thirty-six common beans (Phaseolus vulgaris L.) Genotypes across six contrasting environments defined for its different soil fertility status and located at the southern Ethiopia. The genotypes were arranged in 6 x 6 triple lattice design and executed for two successive main cropping seasons with the objectives to evaluate yield performance of common bean genotypes and identification of mega environments. GGE (i.e., G = genotype and GE = genotype by environment, interaction) bi-plot methodology was used for graphical presentation of yield data after subjecting the genotypic means of each environment to GGE Bi-plot software. The first two principal components (AXIS 1 and AXIS2) were used to display a two-dimensional GGE bi-plot. Thus, genotypic AXIS1 scores >0 classified the high yielding genotypes while AXIS2 scores <0 identified low yielding genotypes. Unlike genotypic AXIS1, genotypic AXIS2, scores near zero showed stable genotypes whereas large AXIS2 scores classified the unstable ones. The environmental AXIS1 were related to crossover nature of GEI while AXIS2 scores were associated with non-cross over GEI. The six test environments in the southern region were divided in to two distinct mega environments (Mega-1 and 2). Mega-1 constituted GOHF13, ARMF12 and ARLF13 while genotype 14 (SCR10) being the best winner, on the other hand, Mega-2 contained GOHF12 and while common bean genotype 20(SCR17) being the best winner. The results of this study indicated that breeding for specific adaptation should be taken as a breeding strategy in southern region to exploit positive GEI to increase production and productivity of common bean.

Purpose. To study the inheritance nature and polymorphism of the performance as well as the traits determining it in intervariety hybrids of common bean (Phaseolus vulgaris L.) and to identify promising genotypes and lines for further practical breeding. Material and methods. The intraspecies F1–F6 hybrid common bean (Phaseolus vulgaris L.) combinations derived from crosses of varieties of different eco-geographical origin (Mavka/CDC Camino, Belko/CDC Rosalee and Mavka/Niger Wally) were studied. The study object was the performance and suitability for mechanized harvesting as well as traits that determine them. The breeding was conducted according to the full breeding design. We conducted multiple individual selections, starting with F2. We used experimental-field and laboratory-analytical methods and statistical processing of data on a PC. Results and discussion. The degree of phenotypic dominance of the plant height in F1 hybrids varied 9.4 to –1.75, of the performance and its constituents – 2.7 to – 1.5. The frequency of probable transgressions in F2 was within 16.5–32.0 and 0–14.7%, respectively, with a coefficient of variation ranging 17.5% to 61.9%. The index traits were less variable. In the F3 Mavka/CDC Camino the share of performance-positive transgressions was 50.0%; in the F3 Belko/CDC Rosalee it was 12.0% related to the number of transgressive forms in F2. In the F4 Mavka/CDC Camino, it increased to 66.1%. 57.1% of the F5–F6 breeding lines gave higher yields than that from check variety Pervomaiska. In 64.3% of the breeding lines, the yield stability exceeded 70%; 39.2% of the accessions were better (81.4–97.1%) than the check variety (76.5%). Conclusions. Intravariety hybridization was proved to be an effective method for the crop breeding. It is recommended to select idiotypes from hybrid populations from crossing forms have contrasting traits, starting with F3; it is advisable to use the harvest index as a selection criterion

Few plant-breeding studies have examined methodology for improving common bean (Phaseolus vulgaris L.) yields by selecting in an intercrop situation. We hypothesized that early-generation testing would be as useful in a maize (Zea mays L.)/bean intercrop as in sole crop for identifying superior bean populations for yield. F2 to F5 bulks of six selected crosses and their F5-derived advanced lines were evaluated in sole crop or intercrop. The F2 and F5 bulks were evaluated together in a preliminary trial in one location, while the advanced lines were evaluated with the F3s in one location, and with the F4s in two locations. Within sole crop, selection of the best three populations, based on F2 performance, provided 67% of the top advanced lines. The rank correlation between average bulk yield across generations and the average line yield was positive and significant. Within intercrop, selection of the best three populations provided 56% of the top advanced lines. The rank correlation between advanced line yield and bulk yield across generations was positive but not significant. Also, the top three F2 populations selected in sole crop produced 89% of the top advanced lines in intercrop. Advanced line performance showed a positive significant correlation with mean F4 bulk performance for grain yield, 100-seed weight and seeds per pod within sole crop, while positive significant correlation was seen with pods per plant and seeds per pod in intercrop. Results indicate that F2 bulk yields can be used to discard the least promising crosses in both cropping systems. Key words: Early generation testing, Phaseolus vulgaris, intercropping
