Agromorphological Evaluation of 44 lines of Mung Bean (Vigna radiata (L.) Wilczek) Introduced in Burkina Faso

Abstract

Mung bean (Vigna radiata L. Wilczek) is an important annual legume which is well suited to dry areas, like Burkina Faso where it is still an orphan legume. The present study was conducted to evaluate 44 mung bean genotypes introduced in Burkina Faso and to determine genetic diversity in this collection using both quantitative and qualitative traits. A field experiment was conducted in an augmented bloc design with three blocks and an extraearly maturing cowpea variety as check. Data were recorded on six (06) quantitative traits and seven (07) qualitative traits. For qualitative traits, diversity was revealed in four parameters including hypocotyl’s color, seed coat color, pods and stem pubescence. Significant genetic variability was revealed among genotypes for all the quantitative characters. Phenotypic coefficient of variation (PCV) was higher than Genotypic coefficient of variation (GCV) for all characters studied indicating the influence of environmental effect on the characters. The GCV and PCV estimates were high for number of pods per plant followed by plant height and hundred seeds weigh. The high heritability coupled with high genetic advanced as percent of mean observed for these traits suggest an important genetic gain in genetic improvement for these characters. The genetic diversity observed was grouped into five clusters. Mungbean lines were grouped into four clusters and the cowpea variety used as check crop in this trial was clustered apart. This genetic diversity, both qualitatively and quantitatively, will help enrich local biodiversity in terms of legumes in general and mung bean in particular and constitutes an important basis for a future mungbean breeding program.

Assessment of Correlation and Path Analysis for Seed Yield and its Component Characters in Greengram [Vigna radiata (L.) Wilczek]

“…The analysis showed that the number of pods/plant, number of seeds/pod, biological yield and harvest index were all positively correlated with seed yield/plant at both the genotypic and phenotypic levels. These outcomes concur with the conclusions of Zida et al [15], Harsh and Priya [16], Thonta et al [17], Salman et al [18], Thanga et al [19], Kate et al [20], Sandhiya et al [21], Sarfaraz et al [22] and Dhunde et al [23].…”

Assess the Magnitude of Genetic Diversity in Advance Breeding Line of Mungbean with Respect to Seed Yield and Component Traits

“…These results suggest that selecting traits with higher PCV and GCV for further breeding efforts could be more effective. These findings align with previous research by Nitesh et al (2017) for seed yield per plant, harvest index, and number of pods per plant, Tushar kumar et al (2019) and Mariyammal et al [11] for seed yield per plant, Ramakrishnan et al [12], Zida et al [13], and Sineka et al [14] for number of pods per plant.…”

Agrophysiological Performance of Mungbean Accessions (Vigna radiata (L.) R. Wilczek) and Nitrogen Balance under Mungbean in Burkina Faso

“…Indeed, the number of days to 50% fowering varied between 33.67 and 47.33 days with an average of about 40 days for all accessions. However, the authors in [16] found that the number of days to 50% fowering varied between 29 and 48 days with an average of 34.46 on mungbean accessions evaluated in Burkina Faso. Furthermore, the cycle of the 15 accessions studied varied from 82 to 93 days with an average of 88 days.…”
