Abstract
In order to know better the heterosis performance, yield and physiological parameters in 112 hybrids (F
1
) and their
parents the study initiated to create recombinational variability for combining ability, the elite barbadense lines DB 533 and DB 534
were crossed during 2007~2008. During two seasons 2008~2009 and 2009~2010 these barbadense crosses were advanced to F2 and
F
3
generations, respectively. The F
3
lines were evaluated for productivity and fiber quality parameters realizing the emphasis laid on
developing ELS (Extra Long Stable) cotton hybrids out of 171 F
3
lines, only those F
3
lines with acceptable fiber strength were
utilized in the study on recombinational variability of combining ability. During 2010~2011 those twenty eight F
4
lines of barbadense
cross DB 533 × DB 534 depending on the higher value of fiber tenacity, were crossed with the selected four hirsutum testers viz., DH
98-27 (T
1
), ZCH 8 (T
2
), 178-24 (T
3
) and DH 18-31 (T
4
) selected based on earlier study. The derived F
1
crosses (28 barbadense lines x
4 hirsutum testers) were compared with the bench mark crosses (two barbadense lines x 4 hirsutum testers) of the heterotic box, best
Bt check hybrid (MRC 6918) and non
Bt
check (DCH 32). Many derived F
1
crosses were found to be more productive than non
Bt
check DCH 32 (48 hybrids) and the
Bt
check MRC 6918 (35 hybrids). The potential crosses like DH 98-27 X (DB 533 x DB 534 F
4
IPS 49), DH 98-27 X (DB 534 x DB 533 F
4
IPS 22) and DH 98-27 X (DB 533 x DB 534 F
4
IPS 52) recorded highest per se
performance for seed cotton yield. These potential crosses recorded highly significant heterosis over mid parent for seed cotton yield.
They also recorded significant heterosis for other physiological parameters. Apart from showing high productivity the potential cross
DH 98-27 X (DB 533 x DB 534 F
4
IPS 49 showed higher value of photosynthetic rate and stomatal conductance. This potential cross
is example for blending of yield characters and physiological parameters

Introduction
Using heterosis (hybrid vigour) to raise yield and fibre
quality of cotton has long been an objective for
researchers and producers (Meredith and Brown 1998).
Heterosis in cotton was reported as early as in 1894
by Mell (cited indirectly from Randhawa and Singh
1994), and the foundation of the modern concept of
heterosis was laid in 1908 by Shull (Randhawa and
Singh 1994). Since then, interspecific, intraspecific as
well as intervarietal heterosis in cotton has been
reported by a number of researchers who depicted
mid-parent heterosis (MPH) from 0.19% to 122.7%
and better-parent heterosis from 0.02% to 93.83% in
lint yield (Turner, 1953; Davis, 1978; Patil and
Chopde, 1985; Gupta and Singh, 1987). Many further
reports have described heterosis in fibre quality,
vegetative and reproductive growth,
and
photosynthetic production in cotton (Bhatt and Rao,
1981; Whisler et al., 1986; Khan, 2002; Chen et al.,
2005). Heterosis studies have driven the release of
many advanced cotton hybrids and large-scale
heterosis utilization, particularly in India and China
(Basu and Paroda, 1995; Wu et al., 2004).
It is reported that the genetic basis for yield heterosis
in cotton is mainly due to additive and dominance
effects (White and Kohel, 1964;White, 1966; Marani, 1968),
