Abstract
The present investigation entitled “Line x Tester analysis over
environments using pistillate lines in castor (Ricinus communis L.)” was
conducted at the Agricultural Research Station, Anand Agricultural University,
Sansoli. The experimental material comprised of five lines viz., ANDCP 06-07,
ANDCP 08-01, SKP 84, SP 1 and VP 1 as well asninetesters namely RG 2275, SI 1,
SI 2, ANDCI 8, SI 5, SI 7, SI 10, JI 398 and JI 401 alongwith their 45 hybrids
derived from line x tester mating design. The 60 genotypes including check
hybrid, GCH 7 were evaluated in a Randomized Block Design with three
replications under four artificially created environments using two sowing dates
in two years. The observations on five randomly selected plants were recorded
for 13 characters viz., seed yield per plant, days to flowering of primary raceme,
number of nodes upto primary raceme, plant height upto primary raceme, days
to maturity of primary raceme, effective length of primary raceme, number of
capsules on primary raceme, number of effective branches per plant, total
number of branches per plant, shelling out-turn, 100-seed weight, Volume
weight and oil content.
