Phenotypic Characterization of Common bean (Phaseolus vulgaris L.) Accessions Conserved at the Genetic Resources and Biotechnology Institute: Experimental Investigation | Chapter 01 | New Visions in Science and Technology Vol. 11

 The researchers wanted to see how different ten accessions from Zimbabwe's Genetic Resources and Biotechnology Institute (GRBI) differed in terms of qualitative and quantitative characteristics. The accessions were planted in three replicates in a Randomized Complete Block Design. To collect qualitative and quantitative traits, the International Board for Plant Genetic Resources (IBPGR) developed the common bean descriptor list. With Hierarchical Cluster Analysis Minitab Release 12.22 and GenStat Discovery 14 software, the quantitative data for the number of days to 50% flowering, plant height, days to maturity, seed size, grain production, and number of seeds per pod were evaluated. Cluster analysis divided genotypes into two primary groups when the dendrogram was partitioned at the 26:22 percent similarity levels. Cluster A had two bean genotypes, whereas Cluster B contained eight genotypes separated into two subgroups. Depending on genotype pairs, groupings, and sub-groups, the genetic closeness of accessions varied substantially. Accessions from different clusters (A and B) had lesser genetic closeness, whereas accessions from the same cluster had higher genetic similarity. There were significant differences (P0.01) in the number of pods per plant, the number of seeds per pod, length, and seed size across the accessions. Based on diverse morphological traits presented by different accessions, it is feasible to determine that morphological variety exists among the 10 common bean accessions. It's also possible to conclude that there are no duplicates among the ten most common bean accessions.

Medicinal Plant Mucuna pruriens: From Farm to Pharma | Chapter 3 | Trends in Pharmaceutical Research and Development Vol. 5

 Mucuna pruriens, commonly known in India as Kaucha, is well-known for its neuroprotective and aphrodisiac properties and has been widely used since ancient times in the Indian Ayurveda System for the preparation of herbal formulations and tonics. Compared to other legumes, Mucuna seeds have a higher amount of L-Dopa and is a promising medication in the treatment of Parkinson's disease, the second most common neurodegenerative condition. The present report focuses on highlighting information on wild mucuna germplasm collected from various geographical regions of India and checked for higher plant growth, seed yield and seed L-Dopa material. For breeding, superior lines were further employed and 69 F1hybrids were produced. Three (3) promising selections have been shortlisted for commercial cultivation with white coloured seed characteristics by back cross lines, Weighing 72-114 gm/100 seeds, yielding 424-810 gm seeds / plant and > 4.5 percent L-Dopa content. Medium-bold in scale. Carbohydrates, protein , fat and minerals such as calcium, phosphorus, iron, potassium and sodium have been tested for the nutritional status of selected 3 lines. Agronomic practise in South Gujarat has been standardised for cultivation. Maximum economic yield (seed yield) was observed with plant spacing of 1 * 1 metre (1.9 metric tonnes / hectare) and 1 * 1.5 metre (1.3 metric tonnes / hectare) with chemical fertiliser level 150:40:0 kg NPK or bio-fertilizer treatment (T4) with commercial product Biopline+Phosphurt plus N: P: K of 100:60:40 kg / hectare and individual plant support (6-8 foot high bamboo poles) method. The harvesting stage was also fixed-up and semi-dried pods were harvested and further drying was carried out under shade.
