Abstract/ Executive Summary:

The experiment was conducted with a view to determine the yield potential of twelve potato varieties for consecutive years during 2009-2011. The mean performance of varieties, generations and their interactions varied significantly. Field performance revealed that the Plant height decreased in all the varieties Raja, Arinda, Patrones, Multa, Asterix, Granola, Felsina, Diamant, Cardinal, Provento, Ailsa and BARI TPS1 in the 4^th generation compared to 2^nd generation (Breeders’ Seed) except Raja and Arinda and it decreased compared to 3^nd generation in Patrones and Felsina. The highest plant vigor was observed in Felsina and Asterix in the 1^st generation, Patrones, Multa and Asterix in the 2^nd generation and Raja and Granola in the 3^rd generation. The highest number of stems per hill was produced by Patrones in all the three generations and the lowest was in Arinda in the 3^rd generation. The highest number of hills per plot was recorded in Asterix and Granola and the lowest in Ailsa and Raja. Significantly higher tuber yield per hill was obtained from Ailsa, followed by Raja, Arinda and Felsina. Patrones produced higher number of tubers per plot in all the three generations while Ailsa produced the minimum which were followed by Felsina, Diamant, Raja and Arinda in all the generations. The yield of different varieties in the 2^nd generation ranged from 11.94 t/ha (Ailsa) to 26.18 t/ha (Asterix) with an average yield of 19.06 tons/ha. However the highest yield potentiality was observed by Asterix followed by Granola, Arinda, Provento and Diamant in the 2^nd generation.

Start Date: 00-00-2009

End Date: 00-00-2011

Program Area: Seed Technology

Commodity: Potato

Objectives:

To determine the yield potential of twelve potato varieties for consecutive 3 years

Methodology:

Breeders seed of twelve potato varieties namely Diamant, Cardinal, Granola, Patrones, Provento, Multa, Raja, Asterix, Felsina, Arinda, Ailsa and BARI TPS 1 developed by the Tuber Crops Research Centre (TCRC), BARI obtained from Breeders Seed Production Centre, BARI, Debigonj, Panchagarh were used in the study. The study was conducted consecutively for three years. Breeder Seed was planted in 2008-09, third generation seed tubers foundation seed obtained from breeder seed were planted in 2009-10 and the 4th generation seed potato tubers or certified seed obtained from third generation were planted in 2010-11. The plant spacing was 60 cm from row to row and 15 cm from tuber to tuber. The unit plots were 4m².4m (9.6m²). Each plot contained 104 hills at the rate of 26 per row. The seed tubers were planted in November in the first, second and third year respectively. The experiment was laid out in the Randomized Complete Block Design with three replications in each generation. Data were recorded on growth and yield. Collected data were transformed into square roots and analyzed with MSTAT-C programe following RCBD two factors. The mean separation was done by Duncan’s New Multiple Range Test at 5% level of significance.

Achievement/Findings:

In the study significantly higher tuber yield per hill was obtained from Ailsa which was followed by Raja, Arinda, Felsina and Patrones. The minimum tuber yield per hill was recorded from BARI TPS1 which was similar to Diamant, Multa and Asterix. The highest yield of tuber per plot was from Granola which was followed by Asterix, Arinda, Diamant and Provento in the first generation. Similar trend was found in the third generation. In the second generation, Provento yielded the highest which was followed by Asterix, Granola and Patrones. Ailsa produced the minimum yield in all the generations, which was followed by Multa and Raja in the 1^st generation, Felsina and Raja in the 2^nd generation and Multa and Felsina in the 3^rd generation. Among the three generations, higher yield was obtained in the 1^st generation, and then it slightly decreased in the 2^nd generation and again increased in the 3^rd generation except in Patrones and Multa. The yield of different varieties in the 1^st generation ranged from 11.94 t/ha (Ailsa) to 26.18 t/ha (Asterix) with an average yield of 19.06 tons/ha. However the highest yield potentiality was observed by Asterix followed by Granola, Arinda, Provento and Diamant in the 1^st generation.
