The heritability of protein and methionine in beans (Phaseolus vulgaris)
The progress and partial results are given of the research on the variability of protein and met. contents in beans.

| description | The progress and partial results are given of the research on the variability of protein and met. contents in beans. Crosses were made between 3 PI lines and Bush Blue Lake 240 (BBL 240), using the latter as female parent. The resulting generations were grown in Wisconsin, USA (1972) in a completely random design and selections of F1 and F2 hybrid material were grown at CIAT, Colombia (1973). Heritability estimates were based on the regression of hybrid material on the parent material. A rat feeding trial was conducted to evaluate the BV of 4 parent lines, with a large variability in protein and met. contents. Frequency distribution of percentage protein indicates the partial dominance for high protein content in hybrids (BBL 240 x PI 207227); broad sense heritability estimative was 69.1 percent, while the narrow sense estimate was 0. The presence of a overdominance component for low protein content was observed in cross BBl 240 x PI 229815. Broad sense heritability was 71.2 percent and narrow sense estimate was 0. There is a possible dominance for high protein content in cross BBL 240 x PI 302542. Broad sense heritability was 31.9 percent and narrow sense estimate, 49.4 percent. A partial dominance was found for low met. content in BBl 240 x PI 207227. Regression analysis showed the difficulty of early selection as all the seed on the F2 plant is segregating, and the environmental effects on the progeny. In the feeding trial, BBL 240 had the highest BV with respect to the level of met. (CIAT) |
