The present investigation, "Evaluation of different genotypes of quinoa (Chenopodium quinoa Willd.) for yield and yield contributing parameters", was conducted to characterize the quinoa genotypes for different quantitative parameters. The experiment comprised thirteen genotypes, and accordingly, a trial was conducted. The experiment was conducted during Rabi, 2018, using Randomized Block Design with three replications under field conditions at All India Coordinated Research Network on Potential Crops, Department of Agricultural Botany, Mahatma Phule Krishi Vidyapeeth, Rahuri. Observations were recorded on five randomly selected plants in each treatment for branches per plant, inflorescence length (cm), inflorescence width (cm), seed yield/ plant (g), seed yield/plot (kg) and seed yield/ha (qtl). Among the genotypes, EC – 507749 (28.43 qtl/ha) recorded the significantly highest seed yield per hectare, which was followed by EC – 507747 (27.59 qtl/ha) & EC – 507743 (26.20 qtl/ha). The increase in seed yield per hectare was due to the increase in inflorescence length (27.06 cm), inflorescence width (22.63 cm) and branches per plant EC – 507749 (42.26).

Random Amplified Polymorphic DNA is cheap and fast molecular technique to identify the genetic resemblances or variations in DNA in various plants. The proposed research work wasintendedto compare the genetic diversification of Amaranthus viridis species in selected regions of Western Ghats in Tamilnadu and Kerala by RAPD analysis.The biometric morphological data among the five A. viridis accessions were compared. Their genomic DNA was isolated and finger prints were obtained using three RAPD markers. The percentage polymorphism, polymorphism information content, effective multiplex ration and resolving power were calculated. UPGMA dendrogram was constructed and their genetic relatedness was compared using Jaccard coefficient.Upon finger printing, 66 bands were counted for the three RAPD primers used,among which 46 bands were polymorphic band numbers from 8 to 21. Percentage of polymorphic bands ranged between 44.44% and 80.77%. EMRvalues for 66 polymorphic loci ranged between 3.56 and 17.01. The UPGMA dendrogram comparing the genomic profiles of the 5 A. viridis accessions using Jaccard coefficient revealed their genetic distances where the maximum Jaccard’s coefficient value observed was 0.96 between AVKATN and AVNEK. Among the 5 selections the peak similarity index (0.9565) was witnessed between AVKATN and AVNEK. The cuurent study revealed that AVKATN and AVNEK had the highest their genetic distances, whereas AVKATN and AVNEK were genetically similar among the 5 A. viridis accessions. Several polymorphic bands which ranged up to 80.77% have proved their genetic variations.

“…(L.)] belongs to the family amaranthaceae and genus Amaranthus. The word "Amaranthus" has derived from Greek language which means "one that does not wither" or "never fading" [3]. The genus Amaranthus consists of a large number of species that differ in morphology, yield and also nutrient status.…”

Aims: In the present investigation 60 different genotypes of vegetable amaranth were analysed for genetic variability in productivity traits and noticeable range of variability were reported in herbage yield and quality. Study Design: The layout of experimental plot was prepared according to augmented block design II (Federer, 1956). Place and Duration of Study: The experiment was conducted in Department of Vegetable Science, College of Horticulture, Bengaluru, UHS, Bagalkot, Karnataka during summer i.e., from January 2020 to March, 2022. Methodology: The experiment consisted of 60 vegetable amaranth genotypes that were collected from KRCCH, Arabhavi, NBPGR New-Delhi, TNAU, Coimbtore and some local collections, the whole plot was divided into 4 blocks, wherein, each block contained 19 beds of 1m × 1m dimension, each representing different genotypes including four check varieties. The genotypes were sown in line at the spacing of 20 cm, accommodating 10 plants per line and hence each bed accommodated 50 plants. All growth and yield parameters were recorded in five randomly selected and tagged plants of each genotype and mean was worked out for further statistical analysis. Variability parameters were worked out as per method given by Burton and Devane [1], heritability in broad sense and genetic advance as percent of mean was calculated according to the formula given Johnson et al. [2]. Results: The phenotypic coefficient of variation and genotypic coefficient of variation was maximum for number of leaves, stem weight (g), Stem to leaf ratio, herbage yield per plant (g), herbage yield per plot (kg), leaf area per plant (cm2) and leaf size (cm2) minimum in case of plant height and stem thickness as shown in table. High heritability was observed for all the traits, except plant height and stem thickness maximum was recorded for Herbage yield per hectare (99.45 %) and minimum was observed for stem thickness (1.07%). High heritability (h2 = 99.45%) with high genetic advance (GA=92.47%) as percentage of mean was observed for herbage yield per hectare which indicated that additive gene effects were more important for that trait. High genetic advance as per cent of mean was observed for herbage yield per plant (g) however, lowest for stem thickness (0.27) Conclusion: Results indicates the preponderance of additive genes and selection will be effective for improvement of these traits having high heritability with genetic advance as percent of mean.
