SCREENING OF ADVANCED EXOTIC LINES OF WHEAT (TRITICUM AESTIVUM L.) TO IDENTIFY HIGH-YIELDING GENOTYPES UNDER LASBELA CLIMATIC CONDITION

Keywords: Harvest, Fertilizer, yield, characteristic, experiment Introduction Agricultural sector is indispensable to the country's economic growth, food security, employment generation and poverty alleviation particularly, at the rural level. Different processes including morphological as well as physiological, which affects each other and happen on multiple growth stages, are responsible for better results of grain yield. [...]from sowing to harvest, many yield components affect grain yield significantly at different growing periods. Previous research experiments in durum wheat reported the primary components of grain yield were thousand grain weight, No. of grains and grain weight spike"1 and plant height (Slafer and Andrade, 1991; Simane et al., 1993) Through an exploration of the vast genetic variability within a diverse gene pool, we have successfully identified germplasms exhibiting specific yield traits tailored to the agro-climatic conditions of Lasbela. Research layout No. of plants per row = 10 No. of rows per genotype = 2 Row to R distance = 10cm Plant to P distance = 10cm Genotype to G distance = 30cm Observations to be recorded following observation will be recorder during the experiment Germination % of seeds, Days to 75% Heading, Anthesis, Physiological maturity, Grain filling duration, Flag leaf area (cm2), Spike length (cm), Plant height (cm), Biological yield (g), Grain yield (g) and Harvest index.
