Abstract
The present investigation on "Inheritance of morpho-physiological traits
for drought tolerance in rabi Sorghum (Sorghum bico/or (L.) Moench)" was carried out
at Sorghum Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, during the
period rabi 2015-2016. The experimental material for generation mean analysis was
developed by crossing two contrasting genotypes for two crosses i.e. RSV 1237 x RSV
1703 and SPVI830 x IS-6427 and comprised P1, P2, F1, F2, 81 and 82 generations. These
different generations were grown in a randomized block design, with three replications
under non stress (Normal) and moisture stress (Rainout shelter) condition during rabi
2015-16. For combining ability analysis, the 48 crosses (F1's) were affected in L x T
fashion by using 4 male sterile lines and 12 restorer lines and resulting 48 hybrids along
with 16 parents were grown in a separate randomized block design, with two replications
during rabi 2015-16.
