INTRODUCTION Embryo defective mutants in Phaseolus vulgaris obtained by Ethyl methanesulfonate (EMS) induction were studied to determine the structural and molecular basis of seed abortion in this species. In the wild-type, the classical pattern of seed development showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue, and seed coat. On the contrarily, EMS mutant ...

Phylogeographic methods provide the tools to accurately access the geographic origin and diversification of crop species. In the present commentary, I urge the common bean community to face those methods and a tree-thinking mentality with regards to the long standing debate of the origin of common bean. Such efforts will ultimately bring back interest into wild bean studies and reinforce the un...

To lower seed yield loss from directly harvested common bean or dry bean, height of the lower pod-bearing nodes needs to be raised. The objective of this greenhouse study was to stimulate lower stem elongation by gibberellic acid (GA3) of dry bean cultivars. Seeds of cv. Matterhorn, erect indeterminate Type II, and cv. Poncho, prostate indeterminate Type III, were dipped in GA3 at 62.5 to 16,00...

Common beans (Phaseolus vulgaris L.) originated in the New World and are the grain legume of greatest production for direct human consumption. Common bean production is subject to frequent droughts in highland Mexico, in the Pacific coast of Central America, in northeast Brazil, and in eastern and southern Africa from Ethiopia to South Africa. This article reviews efforts to improve common bean...

Abstract: IAC 2051 is a common bean (Phaseolus vulgaris L.) cultivar with carioca-type seed coat, mean 1000 weight of 300g, indeterminate semi-upright type II growth habit, slow post-harvest coat darkening, resistance to Fusarium wilt, bacterial blight, and three races anthracnose, yield 2729 kg ha-1.

Morphological features of common bean (Phaseolus vulgaris L.) seeds were measured in five bean cultivars (Akhtar, Ks21189, Ks31169, G11867 and khomein) using digital image analysis. The images of seeds were captured using digital camera (Canon G7). The images were analyzed using image processing toolbox of MATLAB ver. 7.6 software. Morphological features including Area, Perimeter, Major and Min...
