Abstract: Early-maturity potato,with short growth period and high economic benefit,already become one of main crops to increase farmers income.In order to understand genetic character of potato maturity and provide a basis for parental combination of breeding crosses,we analysed the maturity distribution and its correlation with traits related to yield using progenies from six crosses that early-maturity cultivar Zhongshu 3 hybridizes with early-maturity,mid-maturity and late-maturity cultivar,respectively.The results showed that,potato maturity was controled by multi-genes and inherits as quantitative trait and nucleo-cytoplasmic interaction.It was feasible to make crosses between early-maturity female parent and late-maturity parent for selecting progeny with both early-maturity and high yield.It is a good parental material for Zhongshu 3 to make breeding crosses for early-maturity.

Key words: Potato, Maturity, Early-maturity breeding, Parental combination
