Trial cultivation of seven taro G1 clones demonstrated generally consistent growth characteristics, with plant height being the only trait showing significant variation. For propagation, clones L2-9, P-1, L3-4, and O-3 performed best, producing 3.5 to 4.1 stolons per mother plant. Clone O-7 exhibited excessive lateral bud formation, resulting in the development of multiple cormlets, indicating a need for more rigorous mother-plant renewal and subculture management. Regarding plant health, virus testing from generations G1 to G4 consistently yielded negative results. Missing-plant rates in the first three generations ranged from 1% to 4%, while generation G4 reached approximately 8.6%. Despite this increase, the rate remains better than that of typical farmer-saved materials, suggesting that healthy seedlings can sustain strong field performance. Additionally, acclimatization and cultivation assessments were conducted on eight tissue culture-derived ginger clones. After eight months of cultivation, six 'Nanyang' ginger clones produced between 2.3 and 3.1 kg per plant. Although yield differences among the clones were not statistically significant, the number of branches increased compared to the original materials, accompanied by thinner rhizomes. Continued monitoring is necessary to evaluate recovery across subsequent propagation generations.
