White Lupin: An Example of New Crop Development Projects in Maine

Laura C. Merrick

As a grain legume that can be grown in cool climates both for soil improvement in crop rotations and for marketing of its protein rich seeds, white lupin is considered to have tremendous potential for enhancing the sustainability of agriculture in northern latitude regions such as Maine. A variety of lupin-related projects are currently underway through cooperative efforts among the University of Maine, the Maine Department of Agriculture, Food and Rural Resources (MDAFRR), the USDA/ARS, and local farmers, and involve research concerned with (1) agronomic performance (weed control, planting time, density, contribution to soil fertility, etc.); (2) animal nutrition, for use both as a forage and high protein seed meal; (3) germplasm evaluation to assess the adaptability and seed production potential of a diverse collection of lupin cultivars and breeding lines from numerous countries. The lupin projects have been funded in part by the MDAFRR, which has recently initiated a New Crop and Livestock Development Program. Other examples of alternative crops at various stages of development in Maine include cranberries and broccoli. The purpose of the MDAFRR program is to aid in the diversification of Maine's agriculture through coordinated involvement of Government, University, and private business in order to ensure that agriculture in the state remains viable and competitive with national and international trade.

Evaluation of Herbicides for Sweet White Lupin

Richard Leep and Donald C. Penner

Sweet lupins have been known for over 50 years, however, interest in sweet white lupin production in the United States has been recent. No herbicides have been registered for this crop. The purpose of this study was to identify potential herbicides for sweet white lupins. Herbicides at rates generally required to obtain weed control were applied preemergence and postemergence and evaluated in the field. Sweet white lupin was tolerant to preemergence application of clomazone, imazethapyr, metolachlor, linuron, and pendimethalin. Sweet white lupin was also tolerant to postemergence applications of sethoxydim but not to imazethapyr. Field studies indicated tolerance of sweet white lupin to combinations of metolachlor with linuron provided acceptable weed control.

Generation Mean Analysis of Agronomic Traits in Chickpea

Saranga P. Kidambi, Tarlochan S. Sandhu, and Balwant S. Bhullar

This study was conducted to investigate the inheritance of agronomic traits by generation mean analysis in three crosses of chickpea (Cicer arietinum L.) Simple additive-dominance model was sufficient to explain the genetics of number of primary branches and plant height, while digenic interactions were noticed for number of secondary branches (SB), number of days to flowering (DF) and maturity (DM). Higher order interactions and/or linkage were noticed for seed yield per plant (SY) and seed yield components. Marked heterosis and inbreeding depression were observed. Narrow sense heritability estimates were low to moderate depending on the trait. Seed yield per plant was positively correlated with number of pods per plant (PP), seeds per pod (SP), 100-seed weight (SW) and leaflet area (LA). Therefore, PP, SP, SW and LA should be given more weightage in selection schemes to improve SY.
