Pecan과 Shell bark Hickory와의 種間交雜에 의한 有實樹 新品種育種 硏究 = New Superior Variety Pecan Breeding by the Interspecific Hybridization of Pecan-Hickory Hybrid

다국어 초록 (Multilingual Abstract)

Nut trees are one of the most economical oldest and most good and very importance resources of higher quality food and woody timbers, shading or ornamental tree for man, birds and wild animals.
There is needs to desirable and useful for the new improved nut tree breeding and technology programs; production, processing and products of the world to be brought up to date. The author research has prepared for those most easy to grow, harvest and easy to processing and shelling, to keeping nuts kernels good quality, store, import, export, process or manufacture product, as well as biological traits, horticultural characteristics and industrial features, by the interspecific hybrization hybrids.
The desirable and excellent higher quality and quantity of those superior hybrids tree nuts are influenced by many factors.
The author has 32 years experience between 1995 to 1997, a total 2500 crosses between pecan and hickory cultivations selected seedlings between made at the 「Institute of Nut Tree Science」in Suwon Kyunggido Korea, interspecific hybrid 65 seedling selections have been used under the crossed parentages of pistilate pecan between staminate shell bark hickory.
1. Nut characteristics
1) One of the selected superior nuts and trees interspecific hybrids;
The hybrid characteristics of excellent desirable good quality of lager size nuts and kernels or higher kernel percent as well as the nut volume 10.750㎝3, nut weight 6.376g, kernal weight 2.900g and extremely excellent nuts good quality of the kernel precent 45.152%, in other hand the heritability in the hybrids thin nut shell and to good keeping appearance kernels similar to closed pistilate pecan parents, however the heritability in those hybrids lager nut and kernels similar to closed staminate shell bark hickory parents.
2. Nut Tree Characteristics
1) Adaptability;
The improved interspecific hybrid trees, more adaptability hardy to winter cold and heavy clay soils at the Suwon Kyunggido Korea.
2) Fruitfulness;
The superior selected hybrid grafts the tree bear good annual crops start producing at an early age 5∼6 years old.
3) Hardness;
The improved superior selected hybrids the tree winter cold­hardy and escape to late spring frosts injury.
4) Early nut maturity;
The superior selected hybrids; nuts have been mature before and harvest the crop before bad wether set in.
5) Vigor in growth of improved selected hybrids; the lateness in spring growth; thus it is usually preferable that remain dormant relatively late in the spring, because escape to the early spring shoot growth to damaged by late frosts.
