A Study on Morpho-Nutritional Variability Among Lablab Bean Genotypes
Journal Title: American Journal of Agricultural Science, Engineering, and Technology - Year 2021, Vol 5, Issue 1
Abstract
To evaluate the morphological and nutritional variability among six lablab bean (Lablab purpureusL.) genotypes, a study was carried out at Sylhet Agricultural University, Bangladesh and at Bangladesh Agricultural Research Institute (BARI) during mid-July 2014 to mid-March 2015. Significant morphological variations were noted in both seedling and vegetative stages in their growth. In addition, there were three distinct flower and flower wings color viz. white in SB003; violet in SB010, Rupvan, Auto, and Kanchan; and light violet in SB011 were noted among the genotypes. Further, 8 or 9 layers of flower wings were observed among the genotypes  and the inflorescence length varied from 46.40 cm (SB011) to 42.40 cm (SB010). Considering the pod characteristics, pod length and breadth varied from 14.13 cm (SB011) to 8.13 cm(SB010), and 2.68 cm (Auto) to 2.43 cm (SB010), respectively. Significant variations were also noted for pod yield characteristics. The genotype of Kanchan had the highest number of pod/plant (202.7), whereas Auto had the highest pod yield (23.05 t/ha) followed by Kanchan (19.26 t/ha).The study also revealed that pod yield (t/ha) was positively correlated with the number of pods/plant (0.71), pod weight/plant (1.00), individual pod weight (0.65) and pod yield/decimal (1.00) among the genotypes. Furthermore, significant variations were also noted for the nutrient compositions among the genotypes. The analytical experiment shows that Auto had the highest proportion of Cu (15.28 ppm), Fe (122.22 ppm), Mn (40.74 ppm), B (60.60 ppm), S (0.158 %) and Ca (1.67%). In contrast, the genotype of SB003 had the highest amount of Zn (61.86 ppm) and SB011 had Mg (785 %) content. Therefore, the genotypes of Auto and Kanchan would be recommended for cultivation in the Sylhet region of Bangladesh.
