ABSTRACT:

The trial aimed at determining the purity and performance of rice seeds from some seed companies in the North-Western Region of Nigeria, using the Grow-Out-Test during the 2020 and 2021 dry seasons at the National Cereals Research Institute (NCRI), Kebbi station, located at Gwadangaji, Birnin Kebbi. Nine rice variety of Faro 44 certified seed samples were drawn from the submitted samples sent to the Regional laboratory in Zaria from the various seed companies and one sample of Faro 44 breeder seed from NCRI, Badeggi was used as control in the experiment. The experiment was laid out in a Randomized complete Block Design (RCBD) and replicated three times. Data on days to 50 % heading, plant height at harvest, tiller numbers, yield/ha and 1000 grain weight were evaluated and subjected to general linear model of SAS while total number of off-types counted was computed based on the minimum permissible level at 98 % purity for rice certified seed. The results revealed that there was no significant difference between the Faro 44 certified seeds from the selected companies with the control sample in terms of days to 50 % heading and plant height at harvest; while the control had the highest yield value in both 2020 and 2021. Based on the number of off types counted, all samples were considered pass, since none exceeded the threshold value (24), though proper rouging of the seed fields should be encouraged to minimize the off-types count.
