The aim of this study was to examine genetic variability in quantitative traits of newly created field pea hybrids. The researchers studied two cultivars, one line and their F3 and F4 hybrids. The following quantitative traits were analysed: number of pods per plant, number of grains per pod, 1000 seed weight and grain yield. The largest number of pods per plant was recorded for the Baccara × L-CC line hybrid, with a statistically significantly larger (P < 0.01) number of pods per plant than all the other investigated genotypes, lines and hybrids. L-CC line × Baccara, and Saša × L-CC line had a significantly larger (P < 0.05) number of grains per pod. The smallest number of grains per pod was recorded for the Saša and Baccara × Saša hybrid. The genotype vs. year interaction had a significant (P < 0.05) influence on 1000 seed weight. Significantly higher (P < 0.05) 1000 seed weight was recorded for the Baccara genotype, when compared with all other investigated genotypes, lines and hybrids. The lowest 1000 seed weight was recorded for the L-CC line. The genotype × year interaction had a significant influence on the seed yield of field pea. During this research, high seed yields were achieved by the Baccara genotype and Baccara × L-CC line and Baccara × Saša hybrids.

Phenotypic characteristics including morphological, productivity and quality characters, earliness, and resistance to stresses were evaluated in field experiments and, consequently, drought tolerance (estimated by means of 13C discrimination method) and winter hardiness (in provocation test) were tested. Employment of both genetic and phenotypic characteristics allowed identifying promising sources of new genetic diversity. Some Chinese cultivars were considered as potential donors of quality characters, earliness or drought tolerance. The results indicate that new genetic diversity can be found in resources of geographically distant origin.

China Title: Identification of three new resources of resistance to Fusarium head blight in wheat Abstract: Fusarium head blight (FHB) mainly caused by Fusarium species is one of the most important diseases threatening worldwide wheat production. To develop new FHB resistance resources, disease resistances of three new wheat lines L958, L962 and L987 were evaluated over a period of several years. We employed L699 (PI672540) and L661 as the resistant and susceptible control, respectively. Moderate FHB resistance was observed in these three wheat lines, among which the genotype L958 was found a good resource for yield, quality and FHB resistance improvement. In addition, genotype L962 was found to be resistant to powdery mildew, and both L958 and L987 carried the YrL693 gene conferring stripe rust resistance. The study provides promising results for accelerating the resistance breeding of the three wheat lines.

Abstract: This study was conducted to determine the effects of magnetic field (MF) strength on shoot regeneration and Agrobacterium tumefaciens-mediated gene transfer in flax (Linum usitatissimum L.). Seeds of flax cv. Madaras were exposed to different MF strengths (0 - control, 75, 150, and 300 millitesla (mT)) for 24 h by using an electromagnetic generator system fabricated in laboratory conditions. After sterilization, seeds were germinated on MS (Murashige and Skoog) medium in Magenta vessels. Hypocotyl explants excised from 7-days-old seedlings were used for regeneration. GV2260 strain of Agrobacterium tumefaciens was used in transformation studies. Inoculated hypocotyls were cultured on MS medium containing 1 mg/l BAP (6-benzylaminopurine) and 0.02 mg/l NAA (naphthaleneacetic acid) for 2 days by co-cultivation. Then, they were transferred to MS medium containing the same growth regulators, 100 mg/l kanamycin and 500 mg/l Duocid for selection. The presence of the nptII gene was verified by PCR (polymerase chain reaction) analysis in putative transgenic plants. The highest results with respect to shoot regeneration and transformation frequency were obtained from treatments of 75 mT MF strength.

China Title: Fertility analyses of interspecific hybrids between Lagerstroemia indica and L. speciosa Abstract: Interspecific crosses play an important role in gene introgression, plant improvement and speciation. However, poor fertility of F1 generation was commonly found, which hampered backcrossing and ideal progeny generation. To explore useful materials for further breeding programs, sterile hybrids (DD1, FD1, ZD3) from different cross combinations of Lagerstroemia indica and L. speciosa and the fertile hybrid (ZD6) were selected. The results showed that pollen grains of sterile hybrids had no germination ability while ZD6 showed 25.90% pollen germination rate. The morphology of stigmas and their papilla cells showed no apparent difference. Normal pollen tubes could be detected in ovaries of ZD6 and ZD3 24 h after pollination. However, the enlarged ovaries of ZD3 began to abscise at 72 h after pollination, which suggested that the barriers occurred during post-fertilization phases. As a consequence, ZD6 can be used as either male or female parent for further Lagerstroemia breeding programs, while the sterile hybrids may be used as female parent through embryo rescue culture.

China Title: Characterization of one new non-S-RNase of Armeniaca cathayana Abstract: Armeniaca cathayana, a new species described in 2010, belongs to gametophytic self-incompatibility (GSI) system which is under S-allele control. One new non-S-ribonuclease (non-S-RNase) was found in A. cathayana through comparing its nucleotide and amino acid sequences with sequences of the S-allele in Genbank. The BLAST analysis showed that the one new non-S-RNase S68-RNase (GenBank Accession No. MH155952) had the highest 96% nucleotide sequence homology with Prunus webbii non-S-RNase PW1 (EU809938.1). Alignment of deduced amino acid sequences of A. cathayana S68-RNase shared 83% similarity with P. webbii PW1. The new non-S-RNase determined in this study will provide new information to GSI of Rosaceae.
