Abstract

On Station experiments were conducted at ARS (Horticulture), Rajikot, Jumla for two consecutive years (2010/11 and 2011/12) to identify TPS families for seedling tuber production under Jumla condition. Eleven TPS families were evaluated in RCBD with 3 replications. The results showed no significant difference among TPS families in vegetative characters during 2010/11 whereas they differed significantly on yield attributing characters. Number of tubers per plot was the highest (243.33) in No. 903027 and the lowest (72) in No. 902007. Tuber yield per plot was the highest (3.43 kg in No. 903027 whereas the lowest (1.22 kg) in No. 988143. All the vegetative characters except plant height and yield attributing characters were highly significant during 2011/12. The highest emergence (100 %) was observed in No. 904013, 994014 and 988141 whereas the lowest (4733%) in NO. 902007. Ground coverage was the highest (98.33%) in 903035, 994013 and 994014 whereas the lowest (64.33%) in 902007. Number of main stem was observed the highest (3.33) in No. 902007 whereas the lowest (2) in 903027, 903051 and 903135. The highest number of tubers per plot (231.67) was produced by No. 994014 whereas the lowest by 902007 (87.33). The highest tuber yield per plot (4.67 kg) was observed in No. 994013 whereas the lowest (1.85 kg) in 902007. The result showed that
the highest tuber yield (3.25 kg/plot) was obtained from 994013 followed by 903051 (3.24 kg/plot) and 903027 (3.15 kg/plot). Thus, yield potentiality of TPS progenies No. 994013, 903051 and 903027
should further be verified under farmer's field condition in order to draw conclusive results.
