A field research was carried out at the National Wheat Research Program (NWRP) in Bhairahawa, Nepal 2022 to investigate elite durum wheat genotypes and key traits contributing grain yield. The experiment performed an alpha lattice design with two replications. Thirty distinct were assessed, focusing on fourteen quantitative including days booting, heading, maturity, plant height, spike length, peduncle number of tillers per square meter, spikes grains spike, weight thousand kernel weight, yield, biomass chlorophyll content. studied grown under irrigated condition. Genotype NL1779 attained highest yield 3828 kg/ha, followed by NL1769 (3784 kg/ha), NL1772 (3726 NL1789 (3640 kg/ha) NL1784 (3570 kg/ha). Principal components analysis revealed that eight major loadings first principal describe 53.4% total morphological variance Cluster grouped different into four clusters, each cluster showing variation performance for conditions. III is characterized exhibiting meter. Notably, high-yielding NL1779, NL1769, NL1772, NL1789, NL1784, NL1773 identified within this could serve as potential candidates inclusion national breeding program. These superior be recommended environment after further evaluation. Integrating them programs offers opportunity genetic improvement, establishing a robust production system Nepal, meeting growing demand products while promoting dietary diversity sustainable agriculture.

Breeding for nutrient-rich high yielding wheat varieties is one of the most economical and feasible ways to improve micronutrient deficiency ad hoc building better consumer health among rural people South Asia. To identify Zinc (Zn) Iron (Fe) enriched genotypes, 7th Harvest Plus Yield Trial (7th HPYT) 8th (8th both composed 50 genotypes (including two CIMMYT checks " Kachu#1" "Baj#1" Local Check "Gautam") were evaluated in alpha lattice design with 2 replications under timely sown irrigated condition at NWRP, Bhairahawa during 2016/17 2017/18. The grain Zn concentration Fe varies from 23.8 42.4 ppm 20.6 60.6 ppm, respectively. highly significant positive correlation was found between zinc iron (r = 0.74** HPYT r=0.67** HPYT). This relation indicates that it simultaneously micronutrients. In addition, this study reveals thousand grains weight (TGW) has shown 0.3) (r=0.4) non-significant negative -0.1) (r=-0.1) HPYT. As Nepali farmers major trait interest second yield TGW, showed higher TGW (bold grain) feasible. 9 48 than local check variety "GAUTAM" which bio-fortified are capable producing added supplements them. recommended 17 38 8thHPYT based on yield, these lines included national trial further evaluation different agro-ecological domain Nepal. viz., 7HPYT409, 7HPYT410, 8HPYT417, 8HPYT404 7HPYT442 could be used as donor parents breeding program 7HPYT448, 7HPYT418, 7HPYT426, 7HPYT413, 8HPYT415, 8HPYT431, 8HPYT429, 8HPYT407 8HPYT405 would throughout Terai region Nepal, outstanding genotype Terai/plains
