Clonal multiplication area (CMA) for eucalyptsOne hectare clonal multiplication area was raised at Kottappara by planting 52clones which produced more than 50 per cent success in rooting of cuttings (table 17).Out of these, 19 clones belonged to E. tereticornis, 18 clones belonged to E.camaldulensis, two clones to E. urophylla and only one clone to E. pellita. Two cloneswere produced from the local Eucalyptus ‘hybrid’ CPTs grown as control forcomparison. Ten clones were from ITC Bhadrachalam, some of which showedadaptability in <strong>Kerala</strong>. The CMA was also used as Clonal Testing Area (CTA); thegrowth and disease resistance of the clones were monitored in the plot every six months.3.3.2. Disease incidence in Eucalypt clonesThe clones assembled in CMA/CTA were examined for occurrence of leaf blightdisease caused by Cylindrocladium species and pink disease caused by Corticiumsalmonicolor during the season of disease prevalence for three years (Table 18). The twoclones produced from local eucalypt ‘hybrid’ trees were severely infected by leaf blightand pink disease. Most of the clones produced from plus trees identified among28
provenances were free from infection or suffered low infection. Clones which showedfast growth and disease tolerance/resistance consistently for three years were selected andsupplied to the Central Nurseries of <strong>Kerala</strong> <strong>Forest</strong> Department and HNL for establishingtheir CMA for further mass multiplication (Figs. 9-13), and for raising plantations(Fig.14). Out of 42 <strong>KFRI</strong> clones tested in CMA/CTA, 20 clones were finally selected forthis purpose. These clones are listed in Table 19 and their potential yield is provided. Theproductivity potential is very high (10 - >40 m 3 ha -1 yr -1 ) and higher than that of theseedling crop of the best provenances. During 1998-2003, about 1.33 lakh ramets(seedlings) have been supplied to <strong>Kerala</strong> <strong>Forest</strong> Department alone (Table 20).Table 17.
