A study on micropropagated guava lines selected from EEA 18-40 cultivar under field conditions
Main Article Content
Abstract
biotechnological techniques has been based on the
micropropagation of plantlet sections of botanical seed, high
yielding materials, with the purpose of cloning each individual,
so that constituting genetically uniform in vitro plant
lines that are possibly promissory. In the present work a
comparison was made, under field conditions, between
micropropagated lines selected from cv. EEA 18-40, and its
parents propagated by cutting and graft with respect to yield.
The evaluated variables were: fruit number per plant, fruit
weight and yield. The best results were presented by the clonal
lines A-33 and A-9, with 22.8 and 18.8 ton.ha-1 respectively in
the third cycle of production. Concerning genetic improvement
and seed production, the lines selected were A-9 and A-33, for
presenting higher yields, fruit weight and fruit number per
plant than cutting and graft control. The vegetable material
obtained by micropropagation selected allowed to increase
yield in 19.08 ton.ha-1 as average in three cycles of production
compared to its parents propagated by traditional processes.
