Yield and fruit quality of tomato hybrids heterozygous for ripening and color mutant alleles
PESQUISA AGROPECUARIA BRASILEIRA(2005)
摘要
Seven nearly isogenic tomato hybrids, except for their genotypic constitutions in loci nor(A)/nor, rin, og(c) and hp, were tested for fruit yield and quality traits along the parental background lines FloraDade and Mosporist and two commercial rin(+)/rin tomato hybrids (Carmen F-1 and Chronos F-1). The role of the different genotypic backgrounds on these fruit traits was also studied. The genotypes were tested using a randomized complete block design with four replicates and ten plants per plot. The genotypic constitutions nor(+)/nor or rin(+)/rin had no effect on yield related traits. The genotype nor(+)/nor(A) decreased fruit mass mean. Genotypes nor(+)/nor(A), nor(+)/nor and rin(+)/rin delayed the loss of fruit firmness and the development of color. The relative size of the peduncular sear was not affected by these genotypes. The constitution og(c+)/og(c) hp(+)/hp contributed for higher yield and higher fruit mass in the nor(+)/nor(A) hybrid. Fruit firmness and external color in og(c+)/og(c) hp(+)/hp remained unaffected by nor(+)/nor(A). In og(c+)/og(c) hp(+)/hp fruit, early yield was reduced and shelf life was improved by nor(+)/nor(A). Genotypic backgrounds and the interaction background x ripening mutant genes must be taken into consideration when developing new tomato long-shelf life hybrids.
