Abstract

A study on Genetic Diversity, Biomass and Seed Yield of Thai Sunn Hemp (Crotalaria
juncea L.) Germplasm. The experiment was conducted on Korat soil series at Phitsanulok Land
Development Station, Wang thong District, Phitsanulok Province during 2017 to 2020. The first
sub-project on Randomized complete Block Design with 4 replication was used. 6 treatments
application i.e. 1) Northern variety 2) Northeastern variety 3) Central variety 4) Eastern variety
5)Western variety 6)Southern variety. The second sub-project on split plot in Randomized

complete Block Design with 3 replication. The main plot consisted of dark and light seed color.
Six sub plot as the sunn hemp variety. The third sub-project on spilt in Randomized complete
Block Design with 3 replication. The main plot consisted of large and medium seed size. The forth
sub-project on spilt in Randomized complete Block Design with 3 replication. The main plot

consisted of fine-textured soil, medium-textured soil and coarse-textured soil. Six sub plot as the
sunn hemp variety.
Results showed high character on physiology and morphology in the north variety. 3 group
of sunn hemm was group by cluster analysis. The dark color and lark size seed treat on the
coarse-textured soil showed high Genetic Diversity, Biomass and Seed Yield of Thai Sunn Hemp
Germplasm.

Keywords: Genetic Diversity, Biomass, Seed Yield, Sunn Hemp, Germplasm, dark seed color, light
seed color, large seed size, medium seed size, fine-textured soil, medium-textured soil and

coarse-textured soil.
