Abstract/ Executive Summary:

An experiment was carried out at the experimental field of Olericulture Division of Horticulture Research Centre (HRC), BARI, Gazipur, Bangladesh from October 2017 to July 2017-18 to characterize, evaluate and estimate tolerance level collected rootstocks against BW, FW and RKN. Based on horticultural traits and seedling growth attitude, the entries WSM004, WSM005, WSM006 and WSM007 may also be used as alternate rootstocks. The entries- WSS002, WSM004, and WSM005 were found to be resistant against BW. This first-year results, the experiment may be repeated with included some other parameters like- seed yield per plant, number of seeds per fruit and seed vigour, etc.

Keywords: Fruit, Soil health, Soil, Disease, Rootstocks

Location: Olericulture Division of HRC, BAR, Gazipur, Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Diseases, Soil Health

Objectives:

To collect new rootstocks entries, evaluate and characterize alongside assessment of resistance level against aforementioned soil borne diseases; finally, estimation of rootstocks-scion grafting compatibility.

Methodology:

The experiment was carried out at the experimental field of Olericulture Division of HRC, BARI during the winter-summer season of the year 2017-18. There were six rootstocks germplasm namely- WSS001, WSS002, WST003, WSM004, WSM005, WSM006, WSM007 and WSM008 (WSM004 and WSM008 were remain at BARI), collected from different sources used as material. The first time, rootstocks were sown on April 2017 onward for seed multiplication and morphological characterization. Then, in a second time, the seed of rootstocks was sown on April 30, 2018, for seedling evaluation. The tender seedlings of rootstocks were transplanted in a polybag (6”x4” poly bag having loamy soil with compost) at the age of 10-12 days after germination (1-1.5” height). Irrigation and other management were done as and when necessary for the seedlings of the rootstock. For assessing resistance level against BW, FW and RKN; the rootstocks’ seedlings were transplanted 4.6.2018 in sickbed (The sickbed was established by inoculating the soil with a mixture of Ralstonia solanacearum isolates, freshly collected from wilted eggplant plants from different regions of Bangladesh. The population density of the bacteria applied in the bed prior to set up the experiments was estimated at about 3.0 X 109 cfu/ml of water) maintained RCB design with three replications. Relevant data are being recorded for analysis statistically.

Achievement/Findings:

Considering horticultural traits, seed germination percent, seedling growth and establishing attitude, the entries- WSS002, WSM004, WSM005, WSM006 and WSM007 may be used as alternate rootstocks. However, this first year results, the experiment may be repeated with adding some other parameters like- seed yield per plant, number of seeds per fruit and seed vigour, etc.
