Criteria Used in Selection of Locally Best Tea Bushes

Abdul Waheed, F.S.Hamid and Naseer Ahmad

Study on the evaluation of some criteria used in selection of best bushes from NTRI tea garden i.e. selection of best tea bushes, grouping on the basis of initial pruned material and then used immediately to the same bush. The data recorded on bush canopy, plucking points, interval, rounds, yield and further determination by iodine and chloroform tests. Grouping was comprises on 5 categories from (A – E), i.e. 3 to 11 kg above of fresh pruned material. Though the population density was very low in group D and E (29 and 6 only) as indicated in Table 1, but these bushes were selected for further multiplication on the basis of average yield which was maximum in Groups D and E i.e. 3 to 3.5 kg as compare to group A, B, C.1.5 to 2.5kg/bush respectively. Table 1 reveal that amount of pruned material viz a viz (9 to 11 kgs and 11-above) not only increased the bush canopy (160 cm) as compare to Group A (135), Plucking Points (415 and 429) in Group D and E, where as in Groups A, B and C from (135 and 146) respectively. Plucking rounds (6) and interval (3 to 4 weeks) were the same in all the groups. Table 2 shows that Iodine test were also indicated Group (D, E) were rich in starch content, which are responsible for the shoot growth and obtain grades (4 and 6) where as other groups failed to obtained any grades. Table 3 were also resulted for chloroform test in same manner of pruned material i.e. 9 to 11 and 11 kg and above bushes have well in ability of fermentation in both the groups with the grades (2 to 4) and (4 to 2) in groups D&E as compared to others respectively.
