Temple, Steven R.Song, L[Crop improvement and genetic resources in phaseolus vulgaris l. for the tropics]Crop improvement and genetic resources in phaseolus vulgaris l. for the tropics

While symbiotic nitrogen (N2) fixation by G. max and P. vulgaris reduces their need for combined N, N2 fixation under field conditions is rarely maximized. This paper reviews constraints to N2 fixation in these species, then examines the genetic variability recorded for traits affecting N2 fixati...

The bean (Phaseolus vulgaris) cultivar Jules and the PI 207262 line are moderately resistant to Xanthomonas campestris pv. phaseoli in the temperate zone but appeared susceptible in field evaluations in the tropics. Susceptibility to the pathogen was related to environmental factors that caused v...

Data obtained from the international Bean Rust Nursery (IBRN) in 1975-76 showed that none of the 132 cv. and breeding lines tested was resistant to bean rust; however, some were susceptible only in specific geographical regions. CIATs bean program has concentrated its efforts on selecting rust-re...
