분얼형 옥수수 교잡종의 수량특성비교 = Comparison of Yield Characteristics of Hybrids in Tillering Maize (Zea mays L.)

다국어 초록 (Multilingual Abstract)

The objective of this research was to find a useful genetic information for yield characteristics of tillering maize hybrids. Fls were planted under three plant densities at the experimental field of Agricultural College of Chungnam National University. The fresh yield of P1213749//FR805/IK3, FR805/IK3//Waesungri and IK/LE/FR805/IK3 was 7,862kg/10a, 8,290kg/10a and 7,746kg/10a, respectively. The fresh yield of tillering maize hybrids was higher than that of P3394 hybrids. The dry matter yield of P3394 hybrid was 1,430kg/10a with low plant density(4,800p1an1s) and that of PI213749//FR805/IK3 was 1,834kg/10a, the dry weight of FR805/IK3//Waesungri was 1,836kg/10a and that of IK/LE/FR805/IK3 was 1,810kg/10a. Grain yields per 10a of IK/LE//FR805/IK3(783kg) was the highest in 4,800plants/10a, and that of check hybrid was higher than the tillering maize hybrids in 3,600plants/10a, but grain yield per 10a of IK/LE/FR805/IK3 was 752kg, and that of P1213749/Dangjin//IK/LE(699kg) was higher than P3394 hybrid(680kg) with 2,400plants/10a.
