영문 초록

This study was conducted to investigate the inheritance of culm length and straw stiffness, and to observe the relationship between culm length and other agronomic characteristics in barley. Triple bearded club mariout (C. I. 2523) having the characters of short culm length and straw weakness was crossed with three barley cultivars, Gangbori, Olbori and Chalbori having long culm length and straw stiffness. Culm length, straw stiffness and agronomic characters in parents, F₁ and F₂ were investigated the in field. All three barley crosses, C. I. 2523/Gangbori, C. I. 2523/Olbibori and C. I. 2523/Chalbori, showed good fitness to F₂ segregation ratio of 3 long : 1 short in culm length. The short culm length of C. I. 2523 may be controlled by single recessive gene. Culm length showed positive phenotypic and genotypic correlations with each of 3rd and 4th internodes. Culm length was significantly associated with the leaf blade length but not with the leaf blade width. The negative phenotypic and genotypic correlations were observed between culm length and heading date in all three barley F₂ populations. Culm length also revealed significantly positive phenotypic and genotypic correlations with number of grains per spike, grain weight per spike, number of spike per plant, 1,000-grain weight and yield per plant. F₂ analysis suggested that Gangbori carries one recessive gene associated with straw stiffness and chalbori may carry one dominant gene. C. I. 2523/Olbori F₂ showed the segregation ratio of 13 stiff : 3 weak in stiffness of straw, implying the genetic interaction between alleles. Culm length showed highly positive phenotypic and genotypic correlations with the outside diameter of culm and the weight of culm breaking.
