https://doi.org/10.1007/978-3-319-15597-5-treated Puebla 152 did not differ from that in non-treated plants, whereas increased nodule number was found in Negro Argel at high nitrogen levels. The influence of mineral N on the total amount of nitrogen fixed in the two bean cultivars was only slightly different.

Genotypic variation in biological nitrogen fixation by common bean, been reported previously for common bean, were observed only when environmental factors were favorable. Therefore, common bean lines are available, which can support high biological nitrogen fixation. These can be used either directly as cultivars for production or in breeding programmes to enhance nitrogen fixation in other cultivars.

Breeding common bean for improved biological nitrogen fixation,d (.) a breeding procedure that allows maximum genetic gain for N. fixation and recombination with essential agronomic traits is chosen. Breeding lines capable of fixing enough atmospheric N. to support seed yields of 1000-2000 kg ha. have been identified and new cultivars with high N. fixation potential are being released.

Variability in nitrogen fixation of common bean (, L.) intercropped with maize,sing ones averaging between 50–60% of seed N coming from fixation. Bean lines CNF-480, Puebla-152, Mexico-309, Negro Argel, CNF-178, Venezuela-350 and WBR22-3, WBR22-50 and WBR22-55 were ranked as good fixers.

Misconceptions and practical problems in the use of 15N soil enrichment techniques for estimating Nhave discussed some of the criteria to adopt in selecting reference plants, e.g. how to ensure that the reference plant is not fixing N., is absorbing most of its N from the same zone as the fixing plant, and in the same pattern with time, etc. In addition, we have discussed .N labelling materials a

A field evaluation using the ,N isotope dilution method of lines of , L. bred for increased nitrogential nodule mass until after 40 days. The screening criteria used in the selection of the RIZ lines had been largely indirect with other factors such as disease resistance also being included. Progress for increasing N. fixation over good-fixing parental lines such as BAT76 was not significant and
