Abstract
ABSTRACT The present studies were conducted to evaluate Grewia optiva clones for fodder yield and other related traits among nine different clones in lower Shivalik North Western Himalayas. The results demonstrated positive correlations between collar diameter, fresh fodder weight and fuel wood weight. Similarly, diameter at breast height was also strongly correlated with collar diameter, fresh fodder weight and fuel wood weight. Principal component analysis revealed total variability of 77.8% among genotypes contributed by PC-1 (57.3%) and PC-2 (20.5%). The compositions of clusters revealed that the Cluster I contained the highest number of genotypes followed by Cluster II, III, IV and Cluster V. The highest inter cluster values were recorded between cluster II and IV exhibiting wide genetic diversity and crossing between genotypes of these clusters may develop transgressive segregates in the segregating generations and may end up in some promising genotypes for higher fodder and fuel wood productivity. Grewia optiva clones with (C8, C1, and C4) higher fresh fodder and fuel wood productivity were identified.
