Regarding carotenoids content, the genetic basis, heritability and combining ability in six red pepper inbred lines were investigated using full diallel crosses. Both additive and non-additive gene actions govern inheritance of carotenoids content. The mean square of array through variance and covariance analysis (Wr-Vr) was insignificant, which suggest that inbred lines involved in diallel cross may have no epistatic effects. The Vr/Wr graph revealed the influence of partial dominant gene action towards low carotenoids content and the absence of non-allelic interaction. The H2 component was smaller than the H1 and the [H2/4H1] component was 0.187 less than 0.25, indicating unequal proportion of positive and negative alleles in the parents. The estimates of broad and narrow sense heritability for carotenoids content were 0.956 and 0.832, respectively. The variance of general combining ability (GCA) was relatively higher than that of specific combining ability (SCA), which implied that the additive gene effects were predominant as compared to both dominant and epistatic effects for the accumulation of carotenoids in this genetic population. The values of GCA of ‘62024L1’ and ‘62067L2’ were higher than those of the other parents. These 2 inbred lines, therefore, can be considered as useful breeding materials to enhance fruit carotenoids content in other red pepper varieties.

멜론과 참외의 국내 소비 시장이 확대됨에 따라 다양한 F1 품종이 개발되고 있다. 멜론과 참외의 F1 품종의 순도를 검정하기 위해 포장재배 등의 순도검정법이 이용되고 있으나 시간과 노력이 매우 많이 소요되기 때문에 분자마커를 이용한 순도검정법의 개발이 필요하다. 본 연구에서는 멜론의 EST 염기정보로부터 30개의 SNP 프라이머 조합을 고안하여 멜론과 참외의 순도 검정을 위한 HRM분석방법을 개발하였다. 멜론 두 품종과 참외 한 품종의 양친 사이에 HR
