Arachis Hypogaea L

Abstract Genetic variances for yield and several fruit traits for the F5 and F6 generations of an intercultivar peanut (Arachis hypogaea L.) cross were estimated by maximum likelihood procedures from a nested mating design. Estimates of additive and additive by environmental variances were significant for yield and the fruit traits for the cross between the two Virginia (ssp. hypogaea var. hypogaes) cultivars. Estimates of additive by additive variance were essentially zero for all traits; however, estimates of additive by additive by environmental variances were larger than their associated standard deviations for all traits except yield. Narrow sense estimates of heritability over reciprocal crosses and environments ranged from 0.54 for yield to 0.89 for fruit length. Progress from selection in late generations should be expected for this peanut cross.

Arachis Hypogaea L

The peanut (Arachis hypogaea L.) is recognized as one of the most important legume crops globally for its use in human food; it is widely distributed and cultivated in tropical and subtropical regions. The purpose of this study was to evaluate the cryopreservation of five peanut varieties conserved in the INIAP Germplasm Bank, testing cryopreservation methods, evaluating the germination percentage of whole seeds and embryonic shoots. Subsequently, two quantitative variables, shoot length and root, were evaluated. The average germination percentage of varieties and treatments was higher when embryonic axes were isolated with 99.31% than 86.06% seeds. The best germination percentage of the five varieties for seeds and embryonic shoots was obtained by the Peruvian variety with 88.13% and 92.50%. The best treatments by variety for the germination of whole seeds and embryonic axes were obtained by the treatment (desiccation and NL) for whole seeds (GS2) with 95.42% and embryonic axes with 92.83%. Ageing and cryopreservation treatments positively affected germination and seedling vigor in whole seeds and embryonic axes. The two quantitative variables, shoot and root length showed variability between the five varieties; significant differences were observed between the four treatments evaluated for whole seeds and embryonic axes. The three treatments for whole seeds (GS1, GS2 GS3) and the non-cryopreserved control treatment (GSC), as well as the treatments for embryonic axes (GEA1, GEA2 GEA3) and the non-cryopreserved control treatment (GEAC), obtained good survival. They germinate whole seeds and embryonic axes with sprout development (aerial part) and root formation. With the most effective treatments for whole seeds (GS2) and embryonic axes (GEA2), the cryopreservation of the national peanut collection of the INIAP Germplasm Bank could be started.

Groundnuts (Arachis hypogaea L.) is one of the essential food commodities in Indonesia. The use of biofertilizer has been applied to various types of crops. Meanwhile, the effect of using biofertilizer-sludge biogas on groundnuts is yet unknown. This study aims to analyze the seed viability and vigour, yield productivity, the anatomical response of groundnuts, and optimum concentration that could increase the values of each parameter. Treatments given include applying biofertilizer-sludge with 15 levels of treatment concentration compared to groundnuts without biofertilizer-sludge application as a control. The land was divided into 16 beds for each treatment consisting of control, biofertilizer from 10, 15, 30 L/ha, sludge from 12, 24, to 36 ml, and variations dosage of biofertilizer and sludge combined. The parameters observed for viability and vigour include the percentage of seed germination (GP), seed vigor index (SVI) for yield, the value of harvest index (HI), dry weight of the harvest, and root-shoot ratio (R/S). Anatomical responses were observed with stem diameter, stem’s metaxylem diameter, root diameter, root’s metaxylem diameter, and seed diameter. The biofertilizer-sludge results significantly affected HI, R/S values, stem diameter, root’s metaxylem diameter, and seed diameter. This research concluded that the application of biofertilizer-sludge did not significantly affect the seed viability and vigour and the dry weight of the harvest. The application of biofertilizer-sludge in various doses of concentration resulted in a decrease in the stem metaxylem diameter and root diameter compared to the control. A total of 10 L/ha biofertilizer + 24 ml sludge was an optimum concentration to increasing HI and R/S values. For the increasing stem, root metaxylem, and seed diameter, biofertilizer 30 L/ha + sludge 12 ml, sludge 24 ml, and biofertilizer 15 L/ha + sludge 12 ml were the optimum concentrations, respectively.
