Phenotypic Evaluation of Heritability, Agro-Morphological and Yield Characters of Sixteen <i>Amaranthus</i> Linn. Genotypes

Abstract

Abstract:The field experiment was conducted to evaluate the heritability, genetic variance, agro-morphological and yield characters of Sixteen Amaranthus genotypes. The seeds of the sixteen (16) genotypes of Amaranthus evaluated in this study were; NG/AA/MAY/09/027, NG/AA/03/11/010, NG/AO/11/08/042, NG/AO/11/08/039, NG/SA/DEC/07/0423, NG/SA/DEC/07/0412, NGB01667, NGB01601, NGB01283, NGB01271, NGB01276, NGB01259, NGB01644, NGB01234, NGB01613 and NGB01662. The results showed that there were variability performances in growth and yield characters of Amaranthus genotypes. NG/AA/MAY/09/027 and NG/AO/11/08/039 had the best growth characters while NG/AO/11/08/042 had best yield performance compared to other genotypes. The stem length recorded the best heritability estimate of 95.5% while weight of dry leaf, weight of fresh and dry inflorescent had least (47.7%). The plant height had a positive significant correlation with number of leaf (r = 0.53), leaf width (r = 0.57), number of branches (r = 0.56) but a strong positive correlation with stem length (r = 0.97), stem girth (r = 0.75), number of inflorescent (r = 0.68), inflorescent length (0.64) and inflorescent width (r = 0.72). Prin. 1 accounted for the highest variation in growth and yield characters with proportion of 0.3376 and eigen value of 4.7269, while Prin. 14 was the least with proportion of 0.0003 and eigen value of 0.0038. Therefore, there could be genetic improvement of NG/AA/MAY/09/027 and NG/AO/11/08/039 genotypes for further improvement of Amaranthus.

Phenotypic Diversity and Variation of <i>Lonicera caerulea</i> Populations in the Changbai Mountain Alongside the Elevation Gradient

“…As the foundation of genetic diversity research, phenotypic changes can reflect genetic and environmental diversity, and the phenotype is the most intuitive embodiment of genetic variation [11,12]. Phenotypic evaluation is the simplest and most feasible method for detecting the genetic diversity of a population based on the differences in phenotypic traits [13,14]. Estimating genetic parameters using statistical procedures can be used to effectively evaluate intra-and interpopulation genetic diversity of plants under different habitat conditions [15,16].…”

Morphological Characterisation and Cyanide Content Determination in Phaseolus lunatus Linn. (Lima Beans) Accessions

“…[32] and Gepts [33] who reported yield and pattern of color on the skin of the seeds as a factor of biochemical pigmentation process and a characteristics of wild type character of the cultivated species. The early matured accessions can be useful as parental materials in hybridization programs as similarly suggested by Onuoha and Olawuyi, [34].…”
