The highest number of tubers (9.8)

The highest number of tubers (9.8) was produced by meristem derived plants of UK-BNARI after 90 days of transplanting (Fig. 5) while the lowest was produced by UE007 nodal cuttings harvested at 90 days.

The weight of tubers in both meristem and nodal cutting derived plants increased from 30-90 days after transplanting. At 90 days after transplanting, the weight of tubers was at least more than four times that at 30 days and three times that at 90 days after transplanting. The difference in weight of tubers between meristem and nodal cutting derived explants was highly significant (p

The highest number of tubers (9.8) was produced by meristem derived plants of UK-BNARI after 90 days of transplanting (Fig. 5) while the lowest was produced by UE007 nodal cuttings harvested at 90 days.The weight of tubers in both meristem and nodal cutting derived plants increased from 30-90 days after transplanting. At 90 days after transplanting, the weight of tubers was at least more than four times that at 30 days and three times that at 90 days after transplanting. The difference in weight of tubers between meristem and nodal cutting derived explants was highly significant (p<0.05) at 90 days after planting in all the accessions. At 30 and 60 days after transplanting, the difference between the meristem and nodal cuttings was slightly significant only in UK-BNARI. Again the tuber weight was higher (406.7 g) in meristem derived plants of UK-BNARI and lower (127.5 g) in nodal cutting derived plants of UE007.Table 6 presents the percentage dry matter content of tubers of three accessions of sweet potato examined. The statistical analysis revealed highly significant (p<0.01) differences among the accessions. Again, the percentage dry matter was independent of the source of explants used to derive the plants. The local accession (UE007) produced the highest percentage dry matter for plants regenerated from meristem (29.5%) and nodal cuttings (29.6%) followed by SA-BNARI (28.2 and 27.1% for meristem and nodal cuttings derived plants, respectively) and UK-BNARI (25.9 and 23.4% for meristem and nodal cuttings derived plants, respectively), respectively.DISCUSSION
