Abstract/ Executive Summary:

True Potato Seed (TPS) hybriod progenies. such as, Atzimba X DTO 33. Serrana X DTO 33, Serrana X DTO 28. Atzimba X R 128.6 and Atzimba X DTO 28 were tested against tuber propagated promising variety, Multa. Two seedlings per hill at the age of 35 days were transplanted with the spacing of 60 x 30 cm on December 7, 1986. There was no mortality of the seedlings after transplanting, and plant stands were almost similar and even in some cases better than the variety, Multa. Among the progenies, highest yield was produced by Serrana X DTO 28(25.5 t/ha) followed by Atzimba X R 128.6(22.2 t/ha); while the yield of Multa was only 19.4 ton/ha, The lowest yield was produced by Atzimba X DTO 33 (15.9 t/ha).

Keywords: Performance, Potato hybrid progenies, Yield

Location: Agricultural Research Station, Pahartali, Chiuagong

Start Date: 07-12-1986

End Date: 15-03-1987

Program Area: Variety and Species

Commodity: Potato

Objectives:

To evaluate the yield potentials of different hybrid TPS progenies against an established variety in Bangladesh.

Methodology:

An experiment was conducted at the Agricultural Research Station, Pahartali, Chiuagong during 1986-87 with five promising TPS hybrid progenies against (tuber propagated) variety, Multa in thrice replicated randomized block design. The unit plot size was 4.5 X 1.8m. Two seedlings per hill at the age of 35 days were transplanted with the spacing of 60 X 30 cm on 7 December, 1986. Cut tubers of Multa were also planted on the same date. The crop was harvested on 15 March, 1987. N, P K, Sand Zn were applied at the rates of 160,100,160, 20 and 5 kg respectively per hectare. Nitrogen was applied through urea in two installments, the first one at transplanting along with other fertilizers and the second one at 25 days after transplanting. After transplanting, light irrigation was given by a watering can, and subsequent irrigations were given at 25, 45 and 60 days after transplanting. Data were collected on rate of survival, number and height of shoot per hill, ground coverage percentage by eye estimation, yield and grades percentage of tubers measured by potato grader.
