Based on farmers’ preferences, 12 wheat varieties<br />

with contrasting differences for <strong>the</strong> identified traits<br />

were planted in a replicated farmer-managed trial.<br />

At physiological maturity, farmers in both gender<br />

groups were asked to individually select wheat<br />

genotypes based on <strong>the</strong>ir preferred traits and to list<br />

<strong>the</strong> traits <strong>the</strong>y preferred in <strong>the</strong> selected genotypes.<br />

Women farmers gave priority to such traits as<br />

disease and insect pest resistance (Table 3), and <strong>the</strong>n<br />

to chapati making quality and high grain yield.<br />

Male farmers’ top priorities were late heat stress<br />

tolerance, large white grain, and shattering<br />

tolerance. Chapati making quality was a low<br />

priority for this group. The preferences <strong>of</strong> <strong>the</strong>se two<br />

groups may indicate <strong>the</strong> need for developing<br />

varieties based on how <strong>the</strong>y are used in <strong>the</strong><br />

household. Women farmers are usually in charge <strong>of</strong><br />

making bread and storing grain at home, while men<br />

farmers are more concerned with “filling <strong>the</strong> sacks.”<br />

Both gender groups ranked recently released BL<br />

1473 at <strong>the</strong> top (Table 4) due to its early maturity,<br />

lodging tolerance, and bold, white grain. Based on<br />

<strong>the</strong>se results, NARC will speed up seed<br />

multiplication <strong>of</strong> BL 1473. It will also take into<br />

account farmers’ feedback in planning crosses and<br />

selecting populations in <strong>the</strong> breeding program.<br />

Kotounge Village, Bahtapur District, Kathmandu<br />

Valley (mid-hills). During <strong>the</strong> <strong>1999</strong>-<strong>2000</strong> season, a<br />

PVS exercise was conducted in this village, located<br />

at approximately 1500 masl (mid-hills). The main<br />

wheat variety is <strong>the</strong> old, low yielding, and disease<br />

susceptible variety RR-21 (=Sonalika).<br />

A set <strong>of</strong> 10 improved wheat lines and/or varieties<br />

was grown in a farmer-managed trial. A participatory<br />

field day was organized at physiological<br />

maturity to allow farmers to quantitatively assess<br />

<strong>the</strong> cultivars. Thirty farmers (men and women)<br />

ranked <strong>the</strong> wheat variety BL-1473 as <strong>the</strong> top<br />

performer in that set <strong>of</strong> genotypes. Farmers<br />

preferred <strong>the</strong> variety due to its early maturity, bold<br />

seed, good straw yield, high fertility, and lodging<br />

tolerance. BL-1473 yielded 30% more grain than<br />

RR-21.<br />

Based on <strong>the</strong>se results, about 1.2 t <strong>of</strong> foundation<br />

seed <strong>of</strong> BL-1473 were distributed to 60 farmers a<br />

few days before <strong>the</strong> <strong>2000</strong>-2001 crop season began.<br />

We are optimistic that RR-21 will shortly be<br />

replaced by <strong>the</strong> new variety.<br />

Results <strong>of</strong> a survey conducted a few days before<br />

<strong>the</strong> PVS exercise began showed that <strong>the</strong> ratio <strong>of</strong><br />

new, improved vs old varieties (mainly disease<br />

susceptible RR-21) in <strong>the</strong> area was 10% to 90%. We<br />

are optimistic that this ratio will be reversed in<br />

2001-02 and that <strong>the</strong> new variety will be adopted<br />

by farmers in <strong>the</strong> mid-hills, since 95% <strong>of</strong> seed<br />

dissemination occurs from farmer to farmer.<br />

Pakistan<br />

Lack <strong>of</strong> improved varieties, poor technology<br />

transfer, and a deficient seed multiplication system<br />

are mainly responsible for low wheat productivity<br />

in <strong>the</strong> nor<strong>the</strong>rn hill region <strong>of</strong> Pakistan. Ten wheat<br />

varieties and elite lines developed by NARC’s<br />

NWRP and <strong>the</strong> Turkey/<strong>CIMMYT</strong>/ICARDA Winter<br />
