Genetic Analysis of Yield Related Traits in Bitter Gourd (Momordical Charantia L.)

摘要：

Eight agronomic traits of bitter gourd were investigated, such as the first pistillate flower bearing node, the first node of fruit set, total fruit number per plant, the quality of individual fruit, fruit length, width, fruit flesh thickness, and the early season yield. These quantitative traits were controlled by multiple genes. The results demonstrated that heredity of these traits fits into the Mathers additive-dominant genetic model, and the additive genetic effects were more important than the dominant ones. Environmental variance component had more significant effect on fruit diameter, fruit meat thickness, and early yield. Consequently, these three traits should be selected in the latter generations of segregation, in order to minimize selection error due to environmental impact. Five traits including the first pistillate flower bearing node, the node of first fruit set, total number of fruits per plant and the quality of individual fruit had relatively higher narrow-sense heritability. These traits should be selected in earlier generations, in order to enhance the accumulation of beneficial genetic effect.
