Abstract/ Executive Summary:

The field performance of seven sapaota germplasm collected from different regions of Bangladesh and grafted on Khirni (Mimusops hexandra) root stock under central Bangladesh conditions, revealed that MA-003 produced the highest number of fruits per plant (127) followed by MA 007 (115.67), MA-006 (99.33), MA-001 (92.67) and MA-005 (89.00) during first year (1999-2000) of fruiting. But during 2000-2001 and 2001-2002, MA-007 produced the highest number of fruits per plant (295 and 608 fruit per plant, respectively). The highest average number of fruits (608.00) and yield of fruits per plant (21.84 kg) were obtained from MA-007 in three year trial. It produced heavier (69.20g) and bigger size fruits (4.55 cm X 4.80cm) having higher edible per cent (81.24), light reddish brown and soft pulp which were very sweet and good in taste. The germplasm, MA-007 appeared to produce high yield and better fruit quality and may be recommended for commercial cultivation under the climatic conditions of central part of Bangladesh.

Start Date: 00-00-1999

End Date: 00-00-2002

Program Area: Crop-Soil-Water Management

Commodity: Sapota

Objectives:

To study the field performance of seven local germpalsm of sapota in respect of their growth, fruit characteristics and yield potentials under central Bangladesh conditions.

Methodology:

The investigation was carried out in the sapota orchard of Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur during 1999-2000 to 2001-2002. For the present study one year old grafted saplings were planted in July 1994 at a spacing of 5 x 5 m in randomized co mplete block design with 3 replications and relevant data were recorded when the plants became six years old or more. The germplasm MA-001, MA-002 and MA-003 were collected from Hathazari, Chittagong; MA-005 and MA-006 from Daulatpur, Khulna; MA-004 from Swarupkathi, Barisal and MA-007 was from existing sapota plant of former Citrus and Vegetable Seed Research Centre, BARI, Joydebpur, Gazipur and grafted on Khirni (Manilkara hexandra) rootstock. Cowdung, urea, TSP, MP, gypsum @ 30 kg, 400 g, 300 g, 400 g and 80 g, respectively were applied annually per tree in three equal installments. Irrigation, weeding and other intercultural operations were done as and when necessary. Data regarding flowering and harvesting period, yield, and quantitative and qualitative characters of fru its were recorded. Ten ripe fruits per replication were selected randomly for collecting data on quantitative and qualitative traits for each genotype. Qualitative traits we re evaluated by a panel of judges. The edible portion was calculated from fruit weight minus weight of skin, seed and stylers waste divided by fruit weight. The year wise recorded data for different traits were analyzed statistically and analysis of variance (ANOVA) was performed by ‘F’ (Variance ratio) test and treatment means were separated by Duncan’s New Multiple Range Test (DMRT) for interpretation of results. Pooled analysis of three years data was done according to the method described for combined analysis over year by Gomez and Gomez (1984) using statistical software MSTAT C program.
