“…Seeds have a proclivity to shed shortly after physiological maturity. So, the optimal harvest time should balance the rise in the number of physiologically mature seeds in umbels with the decrease in seed number caused by capsule dehiscence over time (Badawi et al, 2010). In Italy, Amalfitano et al (2019).…”

Constraints are reported for the low productivity and quality of onion seed production in Upper Egypt. Therefore, a field experiment was conducted to study the influence of planting date and genotypes on yield and quality of onion seed production under Upper Egypt conditions where high average day /night-time of temperatures (27.4 C and 11.2 C) for two seasons. The results revealed significant interactions between planting date and genotypes on seed yield/plant in both seasons and the number of umbel/plant in the 2 nd season. The highest seed yield (442.25 kg/fed -1 ) was recorded from Giza 20 planted in Early November sowing. Planted onion bulb set early-November increased seed yield (by 9.6% -17.9 % kg/fed) than grown early December. As a result, Giza 20 cultivar in early November in the current study area and other similar agro-ecology areas could be suggested to produce a better seed yield of onion. A principal component analysis was performed to interpret the distance between the genotypes. The average inter-cluster distance was found maximum (154.15) between G1 (Sabeeni) and G4 (Giza 20). The differences between the behavior of the seven studied traits in Giza 6 and Giza Red (Group I) are very weak, while for Sabeeni (Group III) and Shandaweel 1 (Group IV), the extent of the differences between the average traits reaches 26.5 % and 29.2% in 1 st and 2 nd planting dates under the conditions of Upper Egypt, thus considered 2 groups. The interseasonal and intra-seasonal fluctuation in both climatic parameters greatly affected the studied onion traits.

'Bombay Red' is one of the most widely used onion cultivars in Ethiopia. Seed production of this cultivar is expanding among farmers. However, various constraints are reported for the low seed productivity of this cultivar, out of which inappropriate uses of bulb size and intra-row spacing are the most important ones. Therefore, a field experiment was conducted at Bati Futo watershed, Meskan Wereda, Southern Ethiopia under supplemental irrigation in 2012 to find out optimum bulb size and intra-row spacing for quality and economically feasible seed production of the cultivar.
