Abstract: Poor management of sorghum tillers is a significant problem in the Benishangul-Gumuz region of Ethiopia, affecting seed yield and quality. An experiment was conducted to determine the impact of sorghum productive tillers on seed yield and quality. The study involved two Sorghum varieties (Assosa-1 and Adukara) and three plant types per spot. The treatments were aligned as RCBD and CRD in factorial combination, replicated three and four times for field and laboratory experiments respectively. Varieties influenced TSW (P < 0.0001), Number of tiller influenced by number plants head matured for seed production (P ≤ 0.0001), plants height (P ≤ 0.0004), The interaction effects of varieties and number of tillers per plant influenced yields, Panicle length (P < 0.0001). For laboratory experiments varieties influenced Speed of germination (P < 0.0001), number of Dead seeds (P < 0.0001). Number of tiller influenced Speed of germination (P < 0.0001), number of Dead seeds, shoot length (P < 0.004), Vigor index one and Vigor index two (P≤0.05). The interaction effects of varieties and number of tillers per plant influenced Standard germination (P < 0.001). The main shoot plants had the highest number of fertile sorghum heads (86.5), followed by primary tillers (27.08). Secondary tillers had the highest plant height (96.52 cm). The main shoot plant yielded more seeds than primary and secondary tillers, with the shoot exceeding these yields by 302.96% and 1333%, respectively. Primary and secondary tillers had higher percentages of dead seeds than the main shoot plant, 53.5% and 45.2%, respectively. The primary and secondary tillers experienced a decline in seedling vigour index one over different periods, while the main sorghum plant varieties, Adukara and Assosa-1, showed an upward trend. The germination percentages of the primary and secondary tillers were less than the 85% Ethiopian seed standard requirement. Because sorghum tillers lower seed quality, they should be eliminated for seed production. If sorghum is grown for grain production, secondary tillers have the benefit of raising overall yield production.

Abstract: The rapid development of molecular biology tools in insect systematics, invasion research, evolutionary ecology and biodiversity analysis has led to faster and greater progress in understanding insect behavior and biology. Efficient DNA extraction is the foremost step and serves as the vital foundation. Several rapid DNA extraction methods have been established, which are often time-consuming and labour-intensive. Here, a simple, fast, low-cost DNA extraction protocol for common insect samples was developed basing on 28 specimens of 16 insect species (7 ants, 9 bark and ambrosia beetles). The new protocol was shown to be feasible and highly efficient by comparison with commercial kit in terms of DNA yield, purity and PCR sensitivity. The concentration of DNA through the new rapid method was higher than that through commercial kit, whether in ant or beetle samples. A better quality of DNA extracted via kit was indicated by A260/A280 mostly ranging from 1.80 to 2.00. There was little difference between DNA extracted from adult and nymphal insects. PCR sensitivity of extracted DNA using both protocols was comparable. For nested PCR, amplification after two rounds yielded a bright signal using template DNA through both methods. But for PCR using primers of LCO1490 and HCO2198, the success ratio was lower (85.18%). Through BLAST, these amplicons were matched to related data with high identity. By combining this protocol with variable analysis platforms such as common PCR, loop-mediated isothermal amplification, and high throughput sequencing, it could assist insect diagnostics, biological surveys and invasion researches.
