Abstract/ Executive Summary:

Seventeen CIP germplasms, with one improved variety Diamant and one local variety Dohazari Sada were evaluated at Baskhali, Chittagong and ARS, Satkhira, during 2010-11 for their suitability against salt tolerance. Among the CIP clones tested, CIP-124 gave highest yield (12.46 t/ha) and comparatively less affected by the salinity than other germplasm at Baskhali, Chittagong. Due to late planting at Baskhalil, Chittagong, all the clones produced lower yield. At Satkhira CIP-120 gave highest yield (68.21 t/ha) where as Diamant gave lowest yield (27.60). All the CIP germplasm found to be promising against salt tolerance at Satkhira under present experimental condition.

Keywords: Potato,CIP, Salt tolerent

Location: Chittagong and Satkhira

Start Date: 11-11-2010

End Date: 05-05-2011

Program Area: Variety and Species

Commodity: Potato

Objectives:

To select varieties suitable for saline areas.

Methodology:

Eleven CIP germplasms such as CIP-101(301024.14), CIP-102 (301029.18), CIP-104 (301055.53), CIP-108 (376181.5), CIP-111 (380583.8), CIP-112(380606.6), CIP-117 (386292.3), CIP-120 (389429.31), CIP-124 (392781.1), CIP-137 (395193.6) and CIP-139 (396311.1) with one improved (Diamant) and one local variety (Dohazari Sada) were evaluated against salt tolerance at Baskhali, Chittagong. One improved variety (Diamant) with thirteen CIP germplasms such as CIP-101(301024.14), CIP-102 (301029.18), CIP-104 (301055.53), CIP-108 (376181.5), CIP-111 (380583.8), CIP-112(380606.6), CIP-117 (386292.3), CIP-120 (389429.31), CIP-126 (392797.22), CIP-129 (393536.13), CIP-130 (393617.1), CIP-134 (395183.7) and CIP-139 (396311.1) were evaluated against salt tolerance at Satkhira. At Baskhali, Chittagong the crop planted on 07/12/2011 was damage by heavy rainfall and again planted on 9/12/2011 (Fig. 1.12). At ARS, Satkhira the tubers were planted on 29.11.10. Plant spacing was 60 cm X 20 cm, Plot size was 1.2 m X 1.6 m. with RCB design, replicated thrice, Weeding, irrigation, earthing-up and other intercultural operations were done accordingly. The yield and yield contributing characters data were recorded and analyzed statistically. Plant vigor was recorded on 1-5 scale, where 1 is very poor vigor and 5 is highly vigorous. Salinity level of experimental plots soil was analyzed as mentioned in table 1.54. The crop was harvested on 03/03/2011 at ARS, Satkhira and 15/03/2011 at Baskhali, Chittagong.
