Agronomic characteristics and their correlations of Job’s tears(Coix lachryma-jobi L. var. ma-yuen STAPF) collected in Korea

This experiment was conducted to select superior local strains and obtain fundamental datas on the breeding of job’s tears. Five job’s tears local strains collected and first selected were applied in the trial. The following results were obtained from the trial. The leaf sheath was light brown, the leaf blade was green and the stigmatic color was white in Jangseong, Wando, Kimje and Gangjin local strains, but in only Hwasun local strain, the leaf sheath was reddish brown, the leaf blade was brown and the stigmatic color was red. Gangjin local strain, the most early maturing, was on July 1 and August 31 in heading and maturing date, and Jangseong local strain, the latest maturing, was on July 17 and Sept. 28, respectively. Jangseong local strain was the longest and thickest as 173cm and 10.2mm in culm length and stem diameter, but Gangjin local strain was 157cm and 9mm, respectively. Jangseong local strain had the heariest 100 grain weight as 37.4g, while Wando local the most effective tillers as 6.1, but Gangjin local strain had the least tiller as 4.6. Gangjin local strain had the heaviest 100 grain weight as 37.4g, Wando local strain had the lightest as 10.2g. In milling ratio, Jangseong local strain was highest to 70.5%, but Gangjin local strain was lowest to 29.4%, In C. protein content, Hwasun local strain was the largest to 17.4%. In milled grain yield, Jangseong local strain was highest as 423kg per 10a, but Gangjin local strain was lightest as 168kg per 10a. Milled grain yield showed negative correlation with 100 grain weight and positive correlation with another characters excepting C. protein(%). Jangseong local strain was thought to be the most proper strain in the southern part, as this strain was comparatively long culm and late maturation, but stem diameter was thick, so it was strong enough not to lodge and it was possible to harvest in about late Sept., and it was multitiller, high in milling ratio and high yielding.
