Pythium ultimum에 의한 묘립고병에 감수성인 완두품종의 종자는 저항성품종의 종자보다 다량의 환원당이 종자분필물내에 포함되었으며 분필속도도 감수성인 완두품종의 종자에서 더 빨랐다. 묘립고병에 저항성인 완두품종의 종자와 감수성인 품종의 종자분필물에서 모두 Raffinose, Meilbiose, Sucrose, Glucose 및 Fructose가 확인되었으나 Glucose와 Sucrose는 감수성 품종의 종자분필물에서 더 많이 검출되었다. Pythium ultimum균은 감수성인 종자 및 종자분필물에서 더 잘 자랐다.

A new garden pea cultivar, Daehyup 2, was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. It was selected from the cross between Olwandu and Sachulwandu in 1996. The preliminary, advanced, and regional yield trials for evaluation and selection of this cultivar were carried out from 2003 to 2006. It has white flower, yellow cotyledon, absent or very weakly curved pod shape and yellow seed color. It was resistant to virus and powdery mildew disease. The 100 green seed weight of Daehyup 2 was 65.5 g, which was 8.9 g heavier than check cultivar. The sucrose and total sugar contents of fresh pod of Daehyup 2 were 11.1% and 12.5%, respectively, which were 3.2% and 4.3% higher than those of Sachulwandu. The fresh pod yield of Daehyup 2 was similar to that of Sachulwandu with 12.16 ton per hectare in the regional yield trials carried out in three locations of Korea from 2005 to 2006.

The effects of Rhizobium inoculant, nitrogen, phosphorus, and molybdenum on nodulation, dry matter production, yield attributes, pod and seed yields, protein and phosphorus contents in seed of pea (pisum sativum) var. IPSA Motorshuti-3 were assessed by a field experiment. Among the treatments Rhizobium inoculant in combination with 25kg P and 1.5kg Mo/ha performed best in recording number of nodules/plant, total dry matter yield, number of pods/plant, number of seeds/pod, 1000-seed weight, green pod yield, green and mature seed yields of pea. The highest green pod yield of 15.37 t/ha (97.05~% increase over control) and green seed yield of 9.6t/ha (69.31~% increase over control) were obtained by inoculating pea with Rhizobium inoculant in association with 25kg P and 1.5 Mo/ha. The effects of 60 or 120kg N/ha were comparable to Rhizobium inoculant in most cases. There were positive correlations among yield attributes, yield, protein and phosphorus contents in seeds of pea. From the viewpoint of yield attributes, yield, and seed quality, application of Rhizobium inoculant along with 25kg P and 1.5kg Mo/ha was considered to be the balanced combination of nutrients for achieving the maximum output from cultivation of pea in Shallow-Red Brown Terrace Soil of Bangladesh.
