Yield losses due to Uromyces phaseoli were determined in 9 bean var. selected for pustule size: BAT 93, BAT 308, and EMP 81 (type 3 pustules; more than 300 millinicrons in diameter, approx.); Jamapa, ExRico 23, and BAT 883 (type 5 pustules; more than 500 millimicrons in diameter, surrounded by a ...

Nuñas, popping beans (Phaseolus vulgaris L.), burst and expand when heated rapidly. Differences in seed microstructure between popping and conventional (non-popping) bean genotypes conceivably contribute to popping in ñuñas. However, the microstructural characteristics which contribute to the pop...

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...

The study was conducted to investigate genetic variability among 113 aromatic and fine local rice genotypes of which five were exotic in origin. The test genotypes were evaluated for 19 growth traits, yield components, and yield. All the quantitative traits varied significantly among the test gen...
