Correlation analysis for various growth and yield attributing traits in potato (Solanum tuberosum L.) genotypes

Abstract

In the present study twelve potato genotypes collected from various agro-climatic regions of India were evaluated in three diverse environments viz., SKUAST-K, Shalimar, Krishi Vigyan Kendra, Budgam and MRCFC Khudwani during Kharif 2018. The experiments were laid out in complete randomized block design with three replications at each location. From the present study it was observed that economically important trait i.e., total tuber yield hectare-1 (q) showed positive and significant association with plant height (cm), plant spread (cm), number of stems hill-1, leaf area (cm2). Stem diameter (cm) and number of tubers plant-1, but positive and non-significant association with days to initiation of germination, indicating that improvement in yield could be brought about by selection of these component traits.
