Although a higher incidence of ectopic pregnancy has been reported after in vitro fertilization(IVF) and embryo transfer(ET), five ectopic pregnancies in one patient is very rare. We experienced a case of combined interstitial and intrauterine pregnancy as fifth ectopic pregnancies after in vitro fertilization and embryo transfer in one patient with history of bilateral salpingectomy due to previous four tubal pregnancies. Repeated transvaginal ultrasound examinations confirmed heterotopic pregnancy. In IVF-ET, bilateral salpingectomy does not remove the risk of interstitial or cornual pregnancy.

Wheat is one of the most important food crops in the world and provides 20% of nutritional requirement to the consumers in developing countries. The consumption per capita of wheat is persistent but the self-sufficiency has decreased owing to the less competitive world market and double cropping system with rice in Korea. This study was conducted to obtain baseline data on the selection lines with early maturity and good agronomic traits. Geumgangmil, a leading Korean variety, was crossed with CIMMYT’s line, and a DH (double haploid) line was released using pollens of Maize in Mexico. The 71 inbred lines were grown in fields at NICS, Miryang. The culm length of inbred lines were normally distributed from 37cm to 106cm, though that of the P1 (Geumgangmil) was 71 and P2 (CIMMYT’s Line) was 77cm. Especially, some lines were very short and measured below 50cm. The spike lengths of most of the lines were longer than that of P1 (7.5cm), but were normally distributed. The number of spikelet was less than that in P2 (19ea.), but was more than P1(10ea.). The heading day of most of the lines was between P1 (11th April) and P2 (25th April) and the maturity day of the lines was similar to P1 (1st June) but 5 lines showed 2~6 days shorter maturity period than that of P1. However, 20 lines were found to have 2~10 days longer maturity period than that of P2.
