Characterization of Soybean Genotypes on the Basis of Yield Attributing Traits and SSR Molecular Markers | Chapter 07 | Innovations in Science and Technology Vol. 3

 Soybean is well-designed to be a main crop and a vital source of nutrition for both humans and animals. The current study was carried out to distinguish between different soybean genotypes based on morpho-physiological parameters and SSR genetic markers. Data for various morpho-physiological variables were collected from experiments carried out in the field using the RBD design, while molecular work was carried out in the lab using 32 microsatellite markers to see whether there was any conceivable variation among different soybean genotypes. The incidence of significant magnitude of variability was discovered by morphophysiological inquiry. The genotypes were sorted into major and minor clusters using a phylogenetic tree based on morpho-physiological features. There were fifty genotypes in the major cluster, but only three genotypes in the smaller cluster. The marker Satt520 had the most genetic diversity (0.66) and the lowest genetic diversity (0.037) across polymorphic 32 microsatellite markers, with an average of 0.35. The highest PIC value was 0.59, which was planned by the same marker, Satt520, and the lowest was 0.036, which was prearranged by marker Satt557. The average PIC value was 0.32, while the average major allele frequency was 0.69. Data based on microsatellite markers also grouped the genotypes into one major and one minor cluster. The presence of genetic variability among genotypes under examination is confirmed by a molecular analysis based on microsatellite markers. The results of this study could help to improve soybean genotypes and promote high-yielding varieties by incorporating a variety of genotypes with good agronomical qualities into a breeding plan.

Investigating the Effects of Variability in Pozzolanic Properties of Rice Husk Ash on Compressive Strength of Concrete | Chapter 4 | Recent Advances in Science and Technology Research Vol. 7

 Rice husk ash (RHA) is an agro waste and a natural pozzolana that is silica-rich and globally found in abundance. This thesis examined the RHA pozzolanic properties from seven different sources in Nigeria (Ogoja, Abakaliki, Adani, Adikpo, Obubra, Makurdi and Vandikya). The elementary chemical composition of this natural pozzolan is found to differ depending on its location. Samples from Ogoja, followed by Abakaliki, Adani, Adikpo, Obubra, Makurdi and Vandikya, were identified to have the highest pozzolanic properties. Their silica content was found to be 84.55%, 76.3%, 70.12%, 70.11%, 64.67 percent, 55.55 percent, and 48.4 percent respectively. As partial substitutes for ordinary Portland cement, four of the seven samples with the highest pozzolanic values were used at 5, 10, 15, 20, 25 and 30 percent replacement levels. The concrete mix ratio of 1:1.5:3 was adopted and the compressive strength values were found to be in the range of 37-42N/mm2 at 5% RHA, 35-39.5N/mm2 at 10% RHA, 30-34.5N/mm2 at 28 days at 5% RHA, 35-39.5N/mm2 at 10% RHA, 30-34.5N/mm2 Compared to the monitored sample, with a strength value of 15 percent RHA, 27-29N/mm2 at 20 percent RHA, 22-25.6N/mm2 at 25 percent RHA and 21-24N/mm2 at 30 percent RHA   42.64N/mm2. Approx.

A Scientific Study on Genetic Variability of Mango Ginger (Curcuma amada Roxb.) in Kerala State of India | Chapter 10 | Cutting-edge Research in Agricultural Sciences Vol.2

 

Curcuma amada Roxb., popularly known as mango ginger is important as a spice and a source of
starch. The rhizomes are carminative and stomachic and are used in the preparation of salads and
chutneys. The present study is an investigation in to the genetic variability of the species in the state
with reference to the morphological growth and yield characters. The study has shown that the
genetic base of the species in the state is currently sound. However, since the farming patterns are
changing and household farming is declining, care should be taken to see that the natural as well as
traditionally cultivated populations of mango ginger are protected and mango ginger cultivation and its
utilization are augmented so that its genetic diversity is protected and the nutritional and medicinal
properties fully exploited.
