Genotype by trait relations of yield and yield components in aromatic peppers (Capsicum annuum) based on GT biplot

  Drastic changes in random environment and lack of cultivar evaluation and multiple trait assessment across years are major constraints to pepper breeding in derived savanna agro-ecology. Ten genotypes of aromatic pepper grown in randomized complete block design were used to investigate the genotype by trait (GT) biplot analysis and to examine its effectiveness in visualizing fresh fruit yield and yield...

Winter wheat cultivars responses to allelopathic potential of wild barley (Hordeum spontaneum Koch) extracts

  Greenhouse and laboratory studies were conducted to examine the effects of allelopathic potential of wild barley shoot and root extracts on seed germination and seedling growth of five winter wheat cultivars. Plant materials containing 1.8, 3.6, 5.4, 7.2, 9.0 g shoot, and 3, 6, 9, 12, 15 g root were soaked in distilled water for 24 h. Then, the extracts were collected and filtered. Shoot and root extracts...
