        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.

        Inheritance of powdery mildew resistance, fruit bitterness, fruit rind hardness and fruit shape was investigated for breeding high quality and disease resistant varieties from an interspecific cross, between Cucurbita martinezii and C. moschata cv. ‘Wonye
