Genetic Polymorphism in Species and Hybrids of , Revealed by RAPDeans, the international coffee trade is concerned with only two species, . and . However, coffee beans can be produced by many other . species. Therefore, the gene pool, useful for both . and . breeding, is made up of all . species (Berthaud and Charrier, 1988).半圆凿 发表于 2025-3-29 13:57:14
Development of Coffee Trees Resistant to Leaf Minere Campinas, a breeding program aiming at the development of high yielding, leaf miner resistant cultivars with standard arabica cup quality. The main steps of this program are discussed in this chapter.placebo 发表于 2025-3-29 16:28:16
Yongfeng Du,Chao Zhang,Guanghuan Wangic tons during 1995. The supply of coffee consumed world-wide primarily comes from two cultivated species: . and ., which account for 75 and 25% of the world market, respectively. These two varieties are commercially known as “arabica” and “robusta”, respectively.neutrophils 发表于 2025-3-29 23:08:14
Nouredine Bourahla,Abdellatif Hannachiine refers to the behaviour of the line in a series of crosses based on the mean value of the resulting F. hybrids. The performance of a particular cross may deviate from the mean of the GCA, and this deviation is known as the Specific Combining Ability (SCA) (Allard, 1971).愤慨一下 发表于 2025-3-30 00:00:36
