2011
Singh, Mohar | Sharma, SK | Singh, TP | Dutta, M
Factor analysis was carried out on 64 genotypes of urdbean to assess the extent of variation for different characters. Data collected on seventeen quantitative traits were subjected to Principal Factor analysis. There were only seven factors which accounted for maximum percentage to the total variance. In factor one about 50 percent variation was associated with grain yield, harvest index, pods/plant, pod bearing branches/plant, plant height, leaf area and leaf growth rate. Factor 2 accounted almost 20% variation and traits included were harvest index and net assimilation rate. Factor 3, 4, 5 and 7 contained variation for some physiological traits including few yield component characters.
