Cross in 1963, parent Mohawk×Starking Hardy Giant, released in 1984. Male anemone, male and female partially meet, female flowers may give and male flowers loose in late April. Nut elliptic, fruit tip blunt, fruit base circle, average single fruit weight 8.10 grams, yield 57.10%, easy to shell. Kernel golden yellow, ridge ditch wide, ridge ditch on the fruit base part of the deep fissure. Nuts ripened early (around mid-september in anhui), ripened early, appeared young (ABI=0.6), easily changed scab.

Yield analysis: boni began to yield in the 5th year after grafting, and the yield in the 10th year could reach 20 kg.

The parent of Wichita is halbert × Mahan, which was released in 1959. The cultivar is female first type, which can be granted from April to the beginning of May. The powder free period is in the first ten days of May. The self flower can not bear fruit, and the fruit mature period is in the middle ten days of October. It has a long oval shape, a sharp and asymmetric top, a sharp base, a single fruit weight of 7.7g, and a high kernel rate of 64.2%. It is one of the varieties with the highest kernel rate, with golden or brown kernel.

The fruit of this variety is beautiful in appearance, large in shape, early in fruit bearing, easy to desquamate, good in taste and easy to infect scab. Wichita is one of the most widely cultivated varieties in the United States with better adaptability and high yield than Mahan. It is recommended to plant sparsely and keep a good ventilation and light transmission environment to reduce the occurrence of scab. ABI = 0.67, there is obvious big and small year phenomenon.

Yield analysis: Wichita began to bear fruit in the third to fourth year after grafting, and the yield in the ninth year could reach 25 kg.

Schoney's parent is Schley x Barton, which was released in 1968. The breeding unit is American pecan experimental station of American Department of agriculture. The base and top of the nut are blunt, the shell is thin, easy to peel off, the quality is excellent, the weight of a single fruit is 7.1g, the ridge of the seed kernel is narrow, the rate of kernel is 57%, and the seed kernel is golden. In the female type, the pollination period of female flower and male flower is about the beginning of May, and the ripening period of fruit is in the middle of October.

Yield analysis: the yield of Shawnee was about 27 kg in the fifth year after grafting.

In 1980, it was selected by the Subtropical Crop Research Institute of Zhejiang Academy of Sciences. The mother tree is located in the kindergarten of Jinhua District (formerly the Fuyu hospital run by American doctors). For the female first type, the pollination period of female flowers and male flowers is in the middle of May, and the fruit ripening period is late (from the end of October to the first ten days of November), which is not suitable for planting in the area with short frost free period. The nut is medium to large, with a single fruit weight of 9.9g, ovoid, apex and obtuse base; the shell is thick, 10 mm. The kernel is light yellow, full, the kernel rate is 54.2%, the kernel oil rate is 78.7%, and the quality is good.

Yield analysis: the yield of Shawnee was about 27 kg in the fifth year after grafting.

The parent of cardo is Brooks x alley, which was released in 1968. The breeding unit is American pecan experimental station of American Department of agriculture. In the male type, the pollination period of male flowers is at the end of April, the pollination period of female flowers is at the beginning of May, and the fruit ripening period is about October 15. The nuts are oval and olive shaped, with sharp base and top. The weight of single fruit is 6.7g (the fruit is smaller), the kernel rate is 54%, the ridge and groove of kernel is wide, and the kernel is golden. It is easy to be infected with scab. It can be used as pollinator in orchard.

Yield analysis: the yield of single plant of cardo was 35 kg in the fourth year after grafting.

The seedlings were selected and their parents were not known. They were published in 1927. The female flower can be pollinated from April to the beginning of May, while the male flower can be pollinated in the first ten days of May. The average weight of single fruit is 11.36g, the rate of kernel production is 56.4%, the rate of oil production is 62.45%. The kernel has a deep ridge and furrow, the base is cracked, sometimes the base is not full, so the requirement of fertilizer and water management is high. The mature stage of nut is in the middle of October. It is easy to desquamate and resist scab.

Yield analysis: Mahan began to bear fruit in the third to fourth year after grafting, and the yield in the ninth year could reach 25 kg.
