Summary, etc.	Investigations on "Evaluation ef in vitro multiplied accessions of <br/>pineapple (Ananas comosus [L.] Merr.) cv. Mauritius" were carried out in the <br/>Department of Pomology and Floriculture, College of Horticulture, Vellanikkara <br/>during 1997-1999. The major objective of the study was to evaluate the field <br/>performance of tissue culture plants of elite accessions against the tissue culture <br/>plants of unselected bulk and conventional suckers under varied fertilizer doses, to <br/>ascertain the superiority of the former over the later two and to isolate the elite <br/>accessions. <br/>During the early stage of crop growth, sucker derived plants recorded <br/>higher values for almost all the vegetative characters studied, whereas from six <br/>months after planting tissue culture plants of elite accessions were on par with <br/>sucker and showed significant superiority over the unselected bulk. <br/>Total dry matter production as well as dry matter partitioning were higher <br/>for tissue culture plants of elite accessions than tissue culture plants of unselected <br/>bulk. The former also showed early flowering with longer flowering phase than the <br/>later. The fruit and yield parameters also showed superiority of tissue culture plants <br/>of elite accessions over that of unselected bulk and the values were on par with <br/>suckers. Among the elite accessions, TK 3 (Ti) and KT 5 (T2) performed well and <br/>recorded the maximum estimated yield (77.0 tonnes), whereas tissue culture plants <br/>of unselected bulk recorded an estimated yield of 49 tonnes only. There was not <br/>much variation among the treatments in all the quality parameters studied, except <br/>for TSS:Acid ratio <br/>All the tissue culture plants including unselected bulk produced more <br/>number of suckers and slips than sucker derived plants. <br/> <br/>The salient outcome of the present investigation with respect to two <br/>fertilizer doses was that, M, showed significant superiority and recorded a lesser <br/>crop duration of one month than M\ in all TC plants when compared to that of <br/>suckers. <br/>The results of the present investigation undoubtedly proved the <br/>r- <br/>superiority of elite accessions over that of unselected bulk, indicating the importance <br/>of clonal selection for crop improvement. Results also proved the requirement of <br/>higher dose of fertilizers and split application of the same during early vegetative <br/>stage to boost up the growth of plants and to reduce the total duration of the crop. <br/>Among the elite accessions KT 3 and TK 2 performed well than others and hence <br/>can be recommended for further evaluation and yield trials. <br/><br/>
