Assessment of advanced Kenyan selected wheat lines for resistance to the prevailing stem rust races (Puccinia graminis f.sp.tritici) in Kenya

Stem rust (Puccinia graminis f.sp.tritici) of wheat (Triticum aestivum) has caused wheat yield losses in Kenya for years and the trend shows the situation has worsened. The objective of the research was to identify elite genotypes for adult plant and seedling stage resistance. Adult plant resistance study was done under natural conditions in three locations. Scoring was done following the modified Cobbs scale. Seedling...

Correlation and path co-efficient analysis for grain quality traits in F1 generation of rice (Oryza sativa L.)

A study on correlation and path co-efficient analysis was conducted on eleven F1 generation derived from crosses between aromatic and non-aromatic parental landraces genotypes. The results showed that high standard deviation was observed on head rice recovery (16.12) followed by gel consistence (13.81) and milling recovery (10.74). The results also showed that correlation between brown rice length and paddy grain width...
