    Combining ability analysis in cowpea (Vigna unguiculata [L| walp)
    (Kerala Agricultural University, 1998) Sobha, P P; Abdul Vahab, M; Krishnan, S
    Combining ability was studied in a 10 x 10 diallel cross in cowpea for nine important characters. The variance due to general combining ability and specific combining ability showed both additive and non-additive gene action for plant height, primary branches, days to flowering, pod length, pod weight, pods per plant, seeds per pod, 100 seed weight and yield per plant. Among ten parental lines, Arka Garima, VU-18, Selection 2-1, Section 263, Pusa Komal and Kanakamoni were good general combiners for most of the yield components. The hybrids VU-18 x Arka Garima and Selection 2-1 x VS 389 possessed high specific combining ability effects for yield per plant.

    Entry, movement and infection of 32p labelled ralstonia solanacearvm (smith) yabuuchietal. in chilli (capsicum annuum l.)
    (Kerala Agricultural University, Vellanikara, 2001) Baby Lissy, Markose; Abdul Vahab, M; Peter, K V; Kamalam, N V; James, Mathew
    Autoradiography and radioassay techniques were utilized to study entry, movement, growth and multiplication, colonisation and infection of Ralstonia solanacearum in chilli. Radioassay of the inoculated resistant and susceptible varieties of chilli revealed that radioactivity counts were more in susceptible variety than in the resistant variety labelled with 32P at 1 h as well as 24 h of inoculation. This radiotracer technique using 32P labelled bacteria in chilli is a potential tool in such plant pathological studies.

    Evaluation of selected varieties of okra for yield and resistance to yellow vein mosaic
    (Kerala Agricultural University, 1993) Sally K Mathew; Abdul Vahab, M; Devadas, V S; Anitha Cherian
    Seven selected varieties of okra were evaluated foryield and YVMV disease resistance under field conditions for three years at the Department of Olericulture, College of Horticulture, Vellanikkara, Trichur. Considering yield and disease resistance, the performances of the varieties Selection-4 and Arka Anamika were promising.

    Heterosis in bacterial wilt resistant hybrids of brinjal (Solanum melongena L.)
    (Kerala Agricultural University, 1994) Geetha Varghese; Abdul Vahab, M
    Studies on heterosis in three wilt resistant F, hybrids and their six parents for four seasons revealed that two hybrids viz., SM 6-2 x Pusa Purple Cluster and SM 6-6 x SM 132 exhibited significant relative heterosis, heterobeltiosis and standard heterosis for fruit number and yield per plant in most of the seasons.

    Seasonal evaluation of capsicum species and cultivars for oleoresin recovery
    (Kerala Agricultural University, 1999) Mini, C; Abdul Vahab, M; Indira, P
    Evaluation of nine chilli genotypes for oleoresin recovery under ihree different seasons identified Arka Lohit as the highest yielderofoleuresin. Genotypes were higher in oleoresin content during winter. Considering the fruit yield and oleoresin recovery together, summer was the best season for oleoresin yield.
