PATH ANALYSIS IN POTATO (Pages : 20 - 23)

The experiment was conducted at Botanical Research Field at Rajshahi University, Rajshahi, Bangladesh during the rabi crop season of 2007-2008. Ten characters were included in the present investigation to study the variability and correlation coefficient path analysis in potato. The range of variation was pronounced in most of the characters, which indicates that the characters were quantitative in nature and are under polygenic control. High estimates of coefficients of variability, heritability and genetic gain (GA %) for FWP, MSN and FWT that these characters are largely controlled by additive gene action and that straight selection for them would be effective. Yield/plant had a significant positive correlation with PH, NLP and FWT depicted that the characters, namely TFWP have high and positively correlatively towards yield/plant and could be considered as selection criteria in potato breeding program. But path coefficient analysis describes that main shoot number, number of leaves/plant, and fresh tuber weight have high and direct contribution towards final tuber fresh weight/plant could be considered as selection criteria in potato breeding program.
