purpureus (L.) Sweet]" was carried out in the College of Horticulture, Kerala
Agricultural University, Vellanikkara, Thrissur during the period 1999-2000. The
major objectives of the study were to gentically catalogue the available germplasm
and to study the genetic variability, heritability, genetic gain, divergence and
correlation of different traits with yield. Fourty four accessions collected from
different parts of the country were grown in randomised block design with two
replications.
The 44 accessions were catalogued based on the descriptor for hyacinth
bean. Significant differences for the characters days to germination, days to first
flowering, days to 50 per cent flowering, days to first harvest, days to final harvest,
duration of crop, number of pods cluster", pod length, 100 seed weight, girth of
pod, weight of pod, thickness of main stem, length of vine, fruit setting percentage,
number of pods plant", yield plot", shelling percentage, days to vegetable
maturity, crude fibre and crude protein content of pod were noticed among the
accessions. The accession DL-6 was found to be highest yielding and DL-8 was
found to be the earliest flowering.
The highest genotypic coefficient of variation and phenotypic
coefficient of variation was observed for weight of pod followed by number of
pods plant", number of pods cluster", fruit setting percentage, number of pods
plant" and days to vegetable maturity. Accession DL-6 was identified as the most
superior one followed by accessions DL-29, DrAO and DL-66.
