Bronzing was observed in many of the bean trials conducted at Fort Collins (Colorado, USA) during 1982 to study the influence of water and shading stress on photosynthesis and protein content of 3 dry bean var., Roza, Pinto U.I. 111, and Olathe. Bronzing symptoms appeared during the late flowerin...

In the Guatemalan localities of Chimaltenango and Cuyuta (19 and 29 degrees Celsius, resp.), the F2 populations from 6 crosses (ICTA Quetzal x JU 80-11, ICTA Quetzal x San Martin, ICTA Quetzal x Rabia de Gato, JU 80-11 x San Martin, JU 80-11 x Rabia de Gato, and San Martin x Rabia de Gato) were o...

Seed increase of the 1300 accessions from both the cultivated subspecies (coccineus and polyanthus) and the wild forms of Phaseolus coccineus is being carried out at 2 locations of Colombia. In Popayan (1700 m alt., 18 degrees Celsius mean temp., and 2000 mm annual rainfall), 12 plants of each ac...

Preliminary results are given of studies on the inheritance of resistance in 454 bean cv. to Pseudomonas syringae pv. phaseolicola strain 3 and its relationships with other kinds of resistance, evaluated in a collaborative project between National Vegetable Research Station (England) and CIAT. (C...

A total of 18 bean var. with different degrees of rust resistance in the field were subjected to 4 treatments, to obtain high severity of Uromyces phaseoli under low RH. Treatments were (1) greenhouse inoculation, with optimum temp. and RH for disease development, (2) field inoculation in infecti...

Ten bean var. with different seed color and size, ranging from 21 to 42 g/100 seeds, were planted in Rubona, Rwerere, and Karama (Rwanda) to monitor the change in proportion of var. within the mixtures over the course of seasons and compare these changes with pure stand yields. Over 5 seasons the...
