Abstract/ Executive Summary:

A comparative study on growth and yield of six local and exotic lines/varieties of lemon raised on pummelo rootstock was conducted at the Central Research Station of BARl at Joydebpur from July, 1980 to December, 1986. The maximum vegetative growth was observed in local line SC-004 in all the years under study. This line produced the highest number of fruits(240.3) as well as highest yield per plant (18.3kg). The exotic varieties, Lisbon, Eureka and Villafranka were poor yielder. The total acid content varied from 5. 72 (Eureka) to 6. 79% (Villafranka):SC-004 was found superior in consideration' of growth, round the year production and yield. The Line was found to be susceptible to gummosis disease.The variety, Seedless Lemon did not grow well on pummelo rootstock

Keywords: Growth and yield, Lemon varieties/ lines, Pummelo rootstock

Start Date: 00-07-1980

End Date: 00-12-1986

Program Area: Variety and Species

Commodity: Lemon

Objectives:

To study the growth and yield of local and exotic varieties/lines of lemon on pummelo rootstock.

Methodology:

The study was conducted at the Central Research Station of Bangladesh Agricultural Research Institute, Joydebpur during July, 1980 to December, 1986. Three local varieties/lines, namely, SC-004, Seedless Lemon and SC-006 and three renowned exotic varieties, namely, Eureka, Lisbon and Villafranka were included in this study. The scions of all the varieties/lines were grafted in situ on 8 month old local pummelo seedlings in April, 1981. Initially three grafts were made in each pit and finally one graft was allowed to grow. The trial was set up in randomized complete block design with three replications. Plants were spaced 3x3m. Intercultural operations, such as, irrigation, weeding, pruning and training, spraying insecticide and fungicide were done as needed. Data on plant height, base-girth, growth, time of Dowering and harvesting, number of fruit and yield per plant were recorded. Five fruits were taken randomly from each plant and analysed in the laboratory. Data on fruit weight, size, thickness of rind, number of seed, weight of seed, percent juice, percent sucrose and total acid were recorded. Total acid was measured directly by an electrically operated Acid Analyser (Atago Company Ltd. model No.FS-2, Japan) and percent sucrose by a hand refractometer (Atago Company Lid.; Agago N1, brix 0- 32%, Japan).
