“…The species A. persicinum has been described as inhibitor of uredospores germination in Puccinia arachidis Speg. (Ghewande 1990), while A. sclerotigenum has never been reported as an antagonist. However, antifungal action has been described for other Acremonium species such as Acremonium implicatum (J.C.…”

Some endophytic fungal genera in Vitis vinifera, including Acremonium, have been reported as antagonists of Plasmopara viticola. Endophytic Acremonium isolates from an asymptomatic grapevine cultivar Inzolia from Italy were identified by morphological features and multigene phylogenies of ITS, 18S and 28S genes, and their intra-specific genomic diversity was analyzed by RAPD analysis. Culture filtrates (CFs) obtained from Acremonium isolates were tested in vitro for their inhibitory activity against the P. viticola sporangia germination. Among 94 isolates, 68 belonged to the Acremonium persicinum and 26 to the Acremonium sclerotigenum. RAPD analysis grouped the A. persicinum isolates into 15 clusters and defined 31 different strains. The A. sclerotigenum isolates, instead, were clustered into 22 groups and represented 25 strains. All A. persicinum CFs inhibited sporangia germination of P. viticola, while not all those of A. sclerotigenum had inhibitory effect. A different degree of inhibition was observed between strains of the same species, while some strains of different species showed identical inhibitory effect. No correlation was found between RAPD groups and inhibitory activity in both Acremonium species.

“…Mycophagous thrips, Euphysothrips minozzi Bagnall and Dipteron maggots (Patil et al 2000) have also been reported to feed on uredospores of P. arachidis (Kolte 1984). However, no serious attempt has been made to use mycoparasites in the control of rust in peanuts, though sprays of culture filtrate of V. lecanii and P. islandicum were demonstrated to be effective in reducing the rust severity under field conditions (Ghewande 1993(Ghewande , 2009. A new fungal antagonist, Fusarium chlamydosporum Wollenw.…”

“…A large amount of genetic variation in terms of host resistance exists in the wild species, providing genetic diversity for improvement. The origin of most rust resistance genes present in the cultivated sunflower can be traced to wild species mainly H. annuus, H. argophyllus, and H. petiolaris (Hennessy and Sackston 1970, Zimmer and Rehder 1976, 1993, Gulya et al 2000. One line (PS 1089) derived from H. argophyllus × cultivated sunflower and two lines (PS 2011 and PS 2032) derived from H. petiolaris × cultivar crosses are reported to be immune to the prevalent races in India (Sujatha et al 2003).…”

“…On the other hand, genes from poor performing parents may combine favourably well to produce high performing offspring due to favourable SCA effects. Traits such as rust and leaf spot resistance and grain yield have been reported to be controlled by additive and non-additive gene effects 16 , 50 . However, other reports indicated that non-additive gene effects were more important for rust resistance and grain yield 51 , 52 .…”

Groundnut rust caused by Puccinia arachidis Speg. is a major cause of yield and quality losses in groundnut (Arachis hypogaea L.) in the warm-humid tropics including Tanzania. Breeding and deployment of rust resistant cultivars with farmer-preferred attributes will bolster groundnut production and productivity. The objective of this study was to determine the combining ability effects and gene action controlling rust resistance in groundnut genotypes for breeding. Twelve selected and complementary parental lines were crossed in a diallel design, to develop F1 progenies, which were advanced to the F2 for individual plant selection. Thirty-three successful partial crosses and the 12 parents were field evaluated using a 5 × 9 alpha lattice designs with two replications over two seasons in Tanzania. The tested genotypes exhibited significant (P < 0.05) variation for rust resistance, yield and yield-related traits. There existed significant (P < 0.05) difference on the general combining ability (GCA) effect of parents and the specific combining ability (SCA) effect of progeny for the assessed traits indicating that both additive and non-additive gene effects conditioned trait inheritance. The Bakers’ ratios indicated that the non-additive gene effects predominantly controlling rust resistance and yield components. This suggested that transgressive segregants could be selected for improved rust resistance and yield gains in the advanced pure line generations. Genotypes ICGV-SM 05570 and ICGV-SM 15567 were the best general combiners for rust resistance and grain yield. The crosses ICGV-SM 16589 × Narinut and ICGV-SM 15557 × ICGV-SM 15559 were identified as the best specific combiners for rust resistance with moderate yield levels and medium maturity. Genotypes with desirable GCA or SCA effects were selected for further breeding.
