Abstract
The individual palms (77 T, 146 Τ, 149 Τ, 132 D, 88 T, 27T, 117T, 114T, 69D, 99D, 42P and 45P) of Tenera x Tenera (614 T x 614 T, 137 T * 137 T, 323 T * 323 T, 648 T x 648 T, 65T × 323T, 663 T * 699T ) progenies (D- dura, T-Tenera and P-Pisifera), which were yielding more than 125 kg Fresh Fruit Bunches (FFB)/palm/year (average of 2000-01 to 2004-05) were provisionally selected and subjected to bunch component analysis. Among the selected dura fruit palms, 69 D recorded high (24.8%) oil to bunch ratio followed by 99 D (19.4%) and 132 D (19.4%). They are not directly useful for hybrid seed production as their potentiality is confirmed only through progeny testing. The palm number 42P from the cross of 663 T * 699 Trecorded maximum oil to bunch (24.3%) and fruit to bunch (42.9%), whereas 45P showed low values (23.1%) for fruit to bunch. Above pisiferas (45P and 42P) are undesirable for seed production as they showed fairly good fruit set (fertile). Because, sterile pisiferas with very low or zero % fruit set only selected for hybrid seed production. Two Tenera palms (149 Tfrom 614 Tx 614 Tand 114 Tfrom 648 T * 648T showed promising bunch quality components which could be used as parental palms for producing progenies for new seed garden by inter se mating or selfing.
