Seed quality may affect the seed germination and seed vigour index of the crop. The present investigation was carried out to study the impact of various weather parameters on germination percentage, seedling dry weight, seedling vigor index-I and seedling vigor index-II, of seeds collected from Nauni, Saproon and Kandaghat in Solan district of Himachal Pradesh during 2014-15 and 2015-16. Seed quality for different seeds from three locations were evaluated in the laboratory by measuring Germination percentage (%), Root length (cm) Shoot length (cm) Seedling fresh weight (g) Seedling dry weight (g), Viability of seed (%),Electrical conductivity, Vigour index I and Vigour index II. The highest germination percentage was recorded at Saproon (86.9), followed by Kandaghat (83.2) and lowest was recorded at Nauni (70.7). Maximum root length was recorded at Saproon (5.64cm), followed by Kandaghat (5.44cm) and lowest at Nauni (3.94cm). Maximum seedling fresh and dry weights, were also recorded at Saproon (0.334g, 0.054g, respectively and minimum at Nauni (0.266g, 0.040g, respectively. The statistically highest seed viability was recorded at Saproon, (97.57%) followed by Kandaghat (96.28%) and lowest at Nauni (91.37%). The highest vigour index -I (655.89) was recorded at Kandaghat during 2014-15 and lowest (381.8) at Nauni in vigour index-II were recorded 2014-2015.
