1990
Rahman, L. | Shaha, H.K.
In the year 1988-90, 16 experiments of tomato were conducted of which 14 were conducted at Bangladesh Agricultural University (BAU) Farm and the rest 2 experiments were conducted through MCC at Noakhali, one on zonal trial and one on multilocation trial. Among the 14 experiments conducted at BAU Farm (a) one on germplasm, (b) one on F(1) hybrids (c) three on segregating materials (d) three on performance study (e) three on yield trial (f) one on replicated trial (g) one on observation trial and (h) one on zonal trial. In the segregating populations single plant selection (SPS) was practiced on the basis of yield and other characters as compared with their parents as well as standard varieties. In F(2), F(4) and F(5) generation 3, 5 and 2 SPS respectively were selected which produced more than 3 kg fruit yield/plant. Six promising lines BAU/TM 0041, 0046, 0066, 0093 and 0101 were selected which produced fruit yield of more than 75 tons/ha. The lines BAU/TM 0158, 0159, 0163, 0170 and 0171 were also selected having more than 81 tons/ha fruit yield. These will be used in the next year yield trials. From the performance study of F(7) lines, 9 lines found to be superior to all the standard varieties. Besides these 5 AVRDC lines were also selected for use in the crossing programme.
