영문 초록

This study was carried ont to know the nature of the genetic behavior of the culm length and its related characters in wheat (Triticum aestioum) by means of 6×6 half dialle cross with the varieties; Chokwang, georumil, suweon #216, Tung Fang Hung #3, Yungkwang and Chugoku #81. For all the characters studied, additive variance was significant, especially 3rd to 5th internodal lengths was controlled by additive component of genetic variance only. Additive effect was relativeby higher than dominance effect in culm length. The long culm was dominant over short calm length. Both broad and narrow sense heritabilities were high in the calm length. The internodal length was devided into three categories, namely, peduncle length, 2nd internodal length and 3rd to 5th internodal lengths. Peduncle length was mainly controlled by dominance effect, while 2nd internodal length was controlled by both additive effect and dominace effect, 3rd to 5th internodal length was controlled by additive effect only. Only genetic variance due to additive effect was significant for ear length. Both broad and narrow sense heritabilities were high.
