Assessment of level and differences among Vicia faba L. genotypes for their degree of cross-fertilization and for their paternal mating success, based on a polycross field experiment.
Khant Sandar Htet
Faba bean (Vicia faba L) is an important food legume all over the world since it is useful for both human consumption and animal feeding and can be adaptable to many regions. A higher degree of cross fertilization is leading to higher heterozygosity and hence to a higher amount of heterosis and that kind of genotypes might have a higher yield stability. Therefore, hybrid breeding and synthetic breeding are major faba bean breeding categories for yield and yield stability now a day. In this research, we employed a new allele-specific SNP based on a PCR genotyping system developed at KBiosciences. A “complete neighbor balance” design (Morgan, 1987) was used for sowing the polycross with two factors, mother plant or pollen acceptor and father plant or pollen distributor for polycross. To analyze the degree of cross-fertilization and paternal mating success, eight different genotypes with the contribution of six different lines and two F1s were used for a polycross. The six inbred lines had achieved the higher degree of cross-fertilization and the lower paternal mating success. The higher paternal mating success with lower degree of cross fertilization was observed in F1 genotypes. A negative correlation of these two variables and no correlation between paternal mating success and neighborhood proximity of father genotypes were observed in this polycross. A higher negative correlation between degree of cross-fertilization and paternal mating success was occurred at the more heterozygous genotypes.
