This study investigates the germinability of botanical seeds of five different varieties of cassava in order to enhance adequate food security in Nigeria.
Cassava is vegetatively propagated by mature stem by farmers though the wild species are naturally propagated through seeds. However, cassava breeders use botanical seeds to improve the crop for various desirable traits. Therefore, the objective of this study was to determine the germinability of seeds in five cassava populations.
The experiment was conducted at Teaching and Research Farm of Department of Agronomy, University of Ibadan. Open pollinated seeds of five IITA varieties of cassava (TMS-1070593, TMS-1011371, TMS-1070539, TMS- 1011368, TMS-1011412) obtained from the cassava research field of Department of Agronomy, University of Ibadan were used for this study. The seeds in each population were planted in a plot of 1×1m replicated four times. Data were collected on number of emerged seedlings from first day of emergence to transplanting in each. The total number of emerged seedlings was used to estimate the percentage germinability for each experimental unit.
An average germination rate of 64.8 % was obtained across the five cassava populations investigated in this study with variety TMS- 1011412 having the highest germination percentage of 78.3 %. Varieties TMS- 1070593 and TMS- 1070539 had the lowest germination rate of 59% under the same conditions. There was significant difference among the five cassava populations for percentage germination. Days to first emergence ranged between 10 and 12 days after sowing (DAS) in this study. However, there was no significant difference among the five cassava population for days to first emergence.
In conclusion, the parental varieties (TMS-1011368, TMS-1011371 and TMS-1011412) used to develop populations with high rate of seedling emergence in this study could be used as parents in cassava breeding programmes to increase chances of selection of superior genotypes. Moreover, this can also be multiply for adoption and adaptation by small holder farmers and other relevant stakeholders in Nigeria and Sub-Saharan Africa in order to generate more incomes, reduce poverty, end hungers as well as enhancing adequate food security in line with the United Nations Sustainable Development Goals (SDGs).
