Abstract/ Executive Summary:

Nine CIP clones and Lalpakri, Lalashil and Diamant as checked variety were evaluated at Bogra and Rajshahi during 2008-09 for their suitability against drought tolerance. Most of the CIP clones performed better against drought tolerance than the checks variety. Significant differences have been reported among the clones/variety and between irrigation treatments in most traits. In general, as water stress increased, vegetative growth and tuber yield decreased. Considering yield and yield attributes, the CIP clones LB-4 (393077.159), LB-7 (393371.58), LB-9 (396004.337 and LB-14 (396244.12) found promising against drought tolerance.

Keywords: Screening, CIP Clones, Drought

Location: Bogra and Rajshahi

Start Date: 01-09-2008

End Date: 05-05-2009

Program Area: Variety and Species

Commodity: Potato

Objectives:

To develop drought tolerance variety.

Methodology:

For drought tolerance trial, two locations (Bogra and Rajshahi) have been selected considering the climatic condition of Bangladesh. At Bogra, the trial was conducting at Tuber Crops Research Sub-Center. At Rajshahi, the same trial was done at farmer’s field under supervision of BARC and the scientists of TCRC and CIP provided the technical support for conducting this experiments. The protocol of drought tolerance trial has already been established at CPRI, India and the same protocol was followed in Bangladesh trials. At Bogra, 9 CIP clones (LB-1, LB-2, LB-3, LB-4, LB-5, LB-7, L B-9, LB-12 and LB-14) and at Rajshahi, 4 CIP clones (LB-1, LB-2, LB-7 and L B-9) with three checks (Diamant, Lalshil & Lalpakri) were included for drought tolerance trial. Breif of the experiments are shown in below. There are three treatments; T₁: Normal Irrigation as practiced by farmer, T₂: One irrigation after 1st earthing up at 30 DAP and T₃: Two irrigation after earthing up at 30 & 60 DAP. Fertilizers were applied @ 325-220-250-120 kg/ha of Urea, TSP, MP and Gypsum, respectively. Full amount of TSP, MP and Gypsum and 50% of urea were applied as basal and the remaining amount of urea was side dressed at 35 DAP. Weeding, spraying and other intercultural operations were done as and when necessary. The crop was harvested at 90 DAP. All the yield and yield contributing characters data were recorded and were statistically analyzed.Wilting of plants was also recorded on 1 to 5 scales where, 5 is fully expanded/no wilting and 1 is fully wilted.
