Abstract:
Eight families from biparental crosses of apple rootstocks and 12 families from open pollinated Malus spp. were analysed in 2 years for N, P, K, Ca and Mg content of the foliage. Highly significant differences were found between the families for all elements. There were no significant differences between the means of the biparental group and the open pollinated group. Ca and K content were significantly more variable in the open pollinated families compared with the biparental families. It is suggested that this increased variation could prove useful in breeding for efficiency of mineral uptake by apple rootstocks.
