Abstract

Genetic purity is one of the quality criteria required for successful seed production of maize. In hybrid seed production, genetic purity can be contaminated by outcrossing from other varieties or events of inbreeding.  The objectives of the study are to clearly put sources of contaminants at each seed class level and suggest possible recommendations to maintain seed quality and to test the physical and physiological quality parameters of each seed classes. A multistage sampling technique was applied for this survey study. Total sample size of 160 households from all districts was interviewed and both qualitative and quantitative data was generated on constraints of hybrid maize production in western Amhara region. Filed inspection of maize seed production fields was done. Moreover, seed samples were collected from, company one, company two, company three and company four. Seed quality testing was carried out at Adet agricultural research center seed laboratory in 2021 for the collected samples. Mean percentages of quality parameters were computed and used for comparing the formal seed sources. The survey study indicated that maize seed production in the districts is constrained by a variety of related factors; the most important constraints are insufficient supply, delayed delivery, unavailability of preferred variety. The field inspection showed the presence of contaminants of maize seed at parental lines (inbred lines) and hybrid seed production. Seed samples of SC-22 parental lines collected from company two and company one showed standard germination of 30.25 and 76.5%, respectively. The laboratory test indicated that majority of seed samples from different seed sources met the minimum requirements for hybrid maize seed standards.

Abstract

Seed is a vital agricultural resource for enhancing crop production and productivity. However, a variety of variables limit bread wheat seed output and quality, including an insufficient seed rate for early generation seed production. The experiment was conducted in three districts, Adet, Debre Tabor, and Enewari, over two years (2020 and 2021) under rain-fed conditions to determine the optimal seeding rate for early-generation seed classes of bread wheat. Treatments included factorial combinations of five seeding rates (50, 75, 100, 125, and 150 kg.ha-1) and two seed classes, breeder and basic seeds. A randomized complete-block design with three replications was employed. A combined study across years and locations revealed that the interaction effect of seed rate and seed class was not significant (P > 0.05) for the parameters of days to heading, days to maturity, plant height, spike length, seed yield, and seed multiplication ratio. The combined results showed that seed rate had a substantial effect on bread wheat spike length, yield, and seed multiplication ratio. Lower seed rates resulted in a higher seed multiplication ratio at all three locations. Increasing the seed rate from 50 to 150 kg.ha-1 increased seed yield from 2555.2 kg.ha-1 to 3235.2 kg.ha-1, although the difference in seed yield between 125 and 150 kg.ha-1 was statistically insignificant (p>0.05 for the combined study). Finally, seed rates as low as 125 kg ha-1 can be employed for all seed classes to boost early-generation seed output in the three locations and similar agroecologies.
