Abstract/ Executive Summary:

Three off-season golden apple germplasm viz. SD JOY 0001, SD JOY 0002, SD JOY 0003 were collected. and seeds were sown for evaluation at Fruit Research Farm of HRC, BARI, Gazipur during 2011-12. Among the three collected germplasm, seeds of two germplasm SD JOY 0001, SD JOY 0002 were germinated and SD-JOY 0003 failed to germinate. Two germplasm were planted in the field of Fruit Research Farm and evaluated. Among the three collected germplasm the highest plant height (1.20 m), base girth (7.5 cm), plant spread (0.50 m in N-S and 0.45 m in E-W orientation were recorded in SD JOY 0002. Among the three germplasm only SD JOY 0001 produced flower and fruit this year. In case of SDJOY 0001 the first flowering initiated in March 20 and second flash came out on April 25 and showing off-season characteristics. On the other hand in case of SD JOY 0002 no flowering still initiated.

Location: Pomology Division, Horticulture Research Centre, BARI, Gazipur

Start Date: 00-01-2011

End Date: 00-00-2012

Program Area: Variety and Species

Commodity: Hogplum

Objectives:

rTo evaluate, characterize and conserve of off-season golden apple germplasm.

Methodology:

Fruits of three off-season golden apple germplasm were collected from the identified and selected trees and the seeds were sown in the Fruit Research Farm, HRC, BARI, Gazipur. Out of three collected germplasm, all of them were planted in 20 January 2011. Among the three germplasm only the seeds of two germplasm viz. SD JOY 002 and SD JOY 001 germinated and four seedlings of each germplasm were planted in the field in August 2011 and April 2012 respectively. The experiment was laid out in a Randomized Complete Block Design with four replications. Planting distance was 4.0 m x 4.0 m. Manures and fertilizers were applied according to the Fertilizer Recommendation Guide, 2005. Insect and diseases were controlled by schedule spraying with insecticide and fungicide when the infestation was remarkable stage. Data on different plant growth characteristics were recorded and statistically analyzed by using MS-Excel. Tree volume was calculated by using the formula of Castle (1983). Tree Volume= p/6 × plant height × (2r)², where 2r = (East-West spread + North-South spread)/2. The incidence of insect and diseases were also recorded.
