The present investigation entitled “Principal component analysis in rainfed green gram genotypes [Vigna radiata (L.) Wilczek]” was carried out to determine the relationship and genetic diversity among 16 green gram genotypes using principal component analysis for various characters during Kharif, 2019 at Agricultural Research Station, Fatehpur - Shekhawati, Sikar (Rajasthan) under rainfed conduction. Principal component analysis (PCA) depicted that three components (PC1 to PC3) accounted for about more than 90% of the total variation for different characters. | Principal component analysis in rainfed green gram genotypes Vigna radiata L.
