A. PLANT BREEDING1. TITLE MAINTENANCE OF GERMPLASM

OBJECTIVE: To maintain the potato germplasm for further manipulation in thebreeding programmes.

RESEARCH Dr.Syed Ijaz ul Hassan

WORKERS: Rana Aftab Iqbal

Mr.Mudassir Hussain

LOCATIONS: Sahiwal

DURATION: Continuous

TREATMENTS: Genotypes = 150

METHODOLOGY: Date of sowing = 2nd fortnight of October, 2015Design = non replicatedRow to row distance = 75 cmPlant to plant distance = 20 cmPlot size = 6 m × 0.75 m

PREVIOUS YEAR’S

RESULT: 123 genotypes were maintained for manipulation in further breedingprogrammes.

2. TITLE ENHANCEMENT AND SCREENING OF GERMPLASM

OBJECTIVE: To determine the distinguishing characteristics of exotic and localgermplasm.



Mr.Mudassir Hussain

LOCATIONS: Sahiwal

DURATION: ContinuousTREATMENTS: Genotypes = 24 new entries will be screened out

against different biotic and abioticStresses along with 4 commercial checksviz: Kuroda, Asterix, Sante & Simply Red

METHODOLOGY: Date of sowing = 2nd fortnight of October, 2015Design = AugmentedBlocks = 3Row to row distance = 75 cmPlant to plant distance = 20 cmPlot size = 6 m × 0.75 m

The data regarding desirable traits will be recorded. Diseased and off-type plants will be rouged out to produce pure seed potato for furthermanipulation in the breeding programe.

Survey of Black Scurf/Rhizoctonia and common scab disease incidenceof potato, at District Sialkot area for the year 2014-2015.

Sr. No. Source of irrigation % of Rhizoctonia % of Common Scab1 Tube well 5-80 10-40

Survey was conducted during the growing season of Potato crop for the year 2014-2015 inthe adjacent locality of district Sialkot. Twenty farmer’s field survey report revealed that themaximum disease incidence of Rhizoctonia and Common Scab diseases was 80% and 40%respectively. Whereas minimum common Scab disease incidence as 10% was observed in thefarmer’s field. It was noticed that where the potato tubers were treated with the fungicides beforesowing by the farmers, only 5% Rhizoctonia disease incidence was recorded. Use of “Monceren”proved to be most effective in controlling the Black Scurf/Rhizoctonia disease of Potato up to 95%.Maximum yield reduction of potato tuber occurred during this season due to heavy rain fall andinundation in the district Sialkot area and great economical losses were also faced by the farmingcommunity.
