Visual selection for seed yield in the F2 and F3 generations of nine common bean crosses

Autor: PATINO, H. Singh, S.P.

The effect of visual screening for grain yield was studied in 9 bean populations resulting from 3 different crossings (single, 3- way, and modified-double crosses) involving different groups of genetic pools from Central America and the Andes. The best yielding lines in the F2 and F3 generations ...

Male sterility in dry beans

Autor: Singh, S.P. White, J.W. Gutiérrez, J.A.

Thirteen male sterile plants were identified in a yield trial of bean germplasm accession G08063 grown at CIAT-Palmira in 1977. Line G08063 is indeterminate, type III with postrate growth; it is relatively early and produces small white seeds. A fertility score (less than 1.3 sterile, 1.3-2.5 par...

Patterns of genetic diversity in Phaseolus beans

Autor: Schinkel, C. Singh, S.P. Gepts, Paul L.

Progress on the observations regarding genetic variability in some Phaseolus spp. is summarized, based on an analysis of phaseollin and isozime variability. In a group of 270 cv. from Latin America, most of them wild, the variability of 8 loci of isozimes was analyzed. Binding data of 5 of these ...

Heritability of seed yield, 100-seed weight, and days to maturity in high and low soil fertility in common bean

Autor: Urrea, Carlos A. Singh, S.P.

A field trial was carried out in CIAT-Quilichao (Colombia) to determine seed yield heritability, wt. of 100 seeds and days to maturity, in soils with high and low levels of fertilization. Plots were fertilized with 600 and 1800 kg of compost (15-15-15)/ha. The F2 and F3 generations of 22 single c...

Sources of some architectural traits in dry bush beans, Phaseolus vulgaris L

Autor: Singh, S.P. Gutiérrez, J.A.

A brief reference is made to new bean germplasm accessions and breeding lines identified at CIAT with specific architectural traits. Examples are given for type I bush beans with 10 or more nodes on the main stem, erect branching, suppressed branching, short foliage and internodes, lanceolate lea...

Phenotypic correlations between architectural characteristics and grain yield in dry beans as affected by plant density and locations

Autor: Nienhuis, James Singh, S.P.

Studies were conducted at CIAT to measure the phenotypic correlations between several architectural characteristics and yield of dry beans as affected by plant density and environment (location). Four bean cv. were used to represent each bush bean growth habit (I, II, III). All 12 cv. were grown ...
