    Genotype x environment interaction and stability of pre-release cultures and varieties of rice
    (Kerala Agricultural University, 1993) Sreekumar, S G; Gopinathan Nair, V; Balakrishnan Asan, R
    Stability analysis conducted using the data collected from nine genotypes of rice evaluated during IS)8."i, 84, 85, «7and 88 kharif seasons at the College of Agriculture, Vellayani revealed that .ill the nine genotypes were stable for height of the plant. With regard to tillers per plant, Cul.126 (Keinya) and I'avi/Jiom were stable. The genotypes Karthika, Asha, Pavizhom, Cul.25331 and Cul.126 (Kemya) were stable for sheath blight disease, while Karlhika, Cul.25331, Cul.l2(i(Remya) and Cul.4(Aaralhy) were stable for sheath rot disease. Regard ing the grain yield, Karlhika and Cul.4 (Aarathy) can be considered as stable genotypes, since they had higher yield than grand mean along with average response and non-significant deviation from regression.

    Gujarath cowpea 2 (Chharodi 1) - an ideal cowpea variety for intercropping in coconut garden
    (Kerala Agricultural University, 1993) Sreekumar, S G; Gopinathan Nair, V; Balakrishnan Asan, R
    Comparative yield trials were conducted with nine varieties of cowpea for three years during kharif in the interspaces of coconut garden at the Instructional Farm, Vellayani. Based on the comparative yield trials' result, Gujaralh Cowpea 2 (Chharodi 1) variety of cowpea was selected and advanced to farm trial at seven locations in Thiruvananlhapu ram district during kharif 1989 along with C 152 and local variety. The variety Gujarath Cowpea 2 (Chharodi 1), which recorded a highest grain yield in farm trials was recommended for cultivation in the interspaces of coconut garden in Thiruvananlhapuram district during kharif.
