Manifestation the signs of size and placement of nutlets on berries and communication with berry mass

Abstract

Progenies from crosses between cultivars Alpha, Pandora and selections Or 1416-9-12 and Or 1416-7-35 with Alpha served for study specifics of effects of genes of parent genotypes conditioning number and placement of nutlets on berries of hybrids, traits variability, their effect on berry mass and percentage of hybrids with different values of the indices. Self-pollination of Alpha led to strong depression in flesh mass per nutlet and wide range of variation of nutlet number per berry in seedlings. Crossing distant by their origin cultivars Pandora and Alpha favoured exhibiting in the progeny new interrelationships between different alleles of genes that controlled development and distribution of nutlets on berries. This conditioned strong depression in flesh mass per nutlet and berry mass in most hybrids. A strong correlation between berry mass and combination of nutlet number per berry and flesh mass per nutlet (R = 0,92***) was established.
