Analysis on Economic Breeding Values of Usual Sugarcane Parents and Their Crosses

Abstract:

In order to evaluate the genetic character of sugarcane parents and the matching effect of cross combination, the economic breeding values of F₁ groups from 35 families were analysis by means of R Software and Australian family test, including plant height, diameter, number of stalk, cane yield and sugar content. The results showed that among 24 female parents, ROC22, Yuetang 92-1287, Neijiang 03-218, ROC25, HoCP 92- 648 were fit for productive females. Among 18 male parents, Yacheng 84-153, ROC22, Yuetang 00-319 were fit for productive males. The eight families, such as ROC22×Yacheng 84-153, Yuetang 92-1287×Yuetang 00-319, Neijiang 00-318×ROC22, ROC22×Yuetang 93-159, ROC25×Yuetang 93-159, Guitang 00-122×ROC22, Yacheng 97-46×ROC22, and HoCP92-648×ROC26, could be used as productive families, they might be breed new varieties with great economic benefit. So, it is suggested that these parents and families should be extent and used vigorously.
