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.
