Soybean genetics and cultivation

String beans a vegetable of high nutritional quality and there is a tendency in Mexico to increase its consumption. It was therefore the objective of this research to identify varieties of string beans adapted to the Valley of Mexico with different growth habits based on their productivity and quality on two planting dates. An experiment with 36 varieties of beans (31 had a determined growth habit while 5 had an undetermined) was established on May 21 and June 15, 2001 in Texcoco, in the state of Mexico. The flowering dates, date of cutting, physiological maturity, total production, and length of the string beans was noted, as well as the seed yield. The protein and crude fiber content of the string beans were evaluated on the first date of planting (PFS). Significant differences (P£0.01), were found in all the quantified variables. The drop in temperature, the photoperiod and the hydro availability reduced the number of string bean cuts of eight of the PFS and of five of the second. The varieties with undetermined habits had a higher total yield of string beans and seeds. Ejotero 50, OR 900 and US No. 3 varieties had an average higher total yield of string beans in the PFS and may be used in early plantings. US No. 3, E10-1, F2 and E10-2 varieties were outstanding on the second date and may be used in late plantings. During the last two planting dates, Bayo Alteño showed a resistance to diseases and a high string bean and seed yield so it can therefore be planted for a double purpose (string beans and grain) and as a progenitor in genetic improvement of string beans. The obtained yield and quality show that it is possible to produce string beans in the Valley of Mexico.
