(42.63), SD 463 x PP 402 (34.09) and MS 341 x DL
161 (25.90). In case of ascorbic acid in red fruits, SCA
effects were significant and positive in fifteen crosses.
Among these cross combinations two crosses MS 341
x SD 463 and MS 341 x PP 403 involves both parents
with significant and positive GCA effects. The other
crosses showing significant and positive SCA effects
have either one parent with significant and desirable
GCA values or both the parents with non-significant
GCA effects. Best five hybrids based on SCA effect
for ascorbic acid in red fruit were SL 462 x VR 521
(45.17), SD 463 x VR 521 (25.92), MS 341 x PP 402
(24.78), PP 402 x PP 403 (20.37) and MS 341 x SD
463 (18.10).
Out of twenty eight crosses, six crosses showed
significant and positive SCA effects for capsaicin in
powder. The significant hybrids based on SCA effects
are SL 461 x VR 521 (0.40), DL 161 x PP 402 (0.38),
MS 341 x PP 403 (0.13), SL 462 x SD 463 (0.07) and
SL 461 x PP 402 (0.05). Similarly for oleoresin
content, 12 crosses recorded significant and positive
SCA effects. Among these crosses, three cross
combinations SL 461 x PP 402, SL 461 x PP 403 and
PP 402 x VR 521 involved both the parents with
highly significant and positive GCA effects. Thus,
these crosses showing both the parents with
significant and desirable GCA effects could serve as a
source material to derive true breeding lines with high
oleoresin content from the segregating populations.
Top five hybrids on the basis of SCA effects were SL
461 x PP 403 (5.71), MS 341 x VR 521 (5.54), SL 461
x PP 402 (3.77), DL 161 x SL 462 (3.76) and SL 461 x
SL 462 (3.27). Out of twenty eight crosses, seven
crosses showed significant and positive SCA effects
for capsaicin in oleoresin. Among these, the cross
combination DL 161 x PP 402 displayed significant
and positive SCA effects, also involved both the
parents with significant and desirable GCA effects.
Best five hybrids based on SCA effects were SL 461 x
VR 521 (1.70), DL 161 x PP 402 (1.60), MS 341 x PP
403 (0.53), SL 462 x SD 463 (0.32) and SL 461 x PP
402 (0.21).For colouring matter in powder, thirteen
crosses out of twenty eight crosses showed significant
and positive SCA effects and thus were adjudged as
good specific combiners. Top five hybrids on the basis
of SCA effects were SL 461 x VR 521 (43.22), SD
463 x VR 521 (26.18), MS 341 x SD 463 (25.55), SL
461 x PP 402 (22.40) and MS 341 x PP403 (20.22).
For colouring matter in oleoresin, the cross
combinations SL 462 x PP 403 and PP 403 x VR 521
showed positive and significant SCA values and
involved both the parents with highly significant and
desirable GCA effects. Top five hybrids on the basis
of SCA effects were PP 403 x VR 521 (191.26), DL
161 x SL 462 (165.87), SL 461 x PP 402 (149.75), SL
462 x SD 463 (140.60) and SL 462 x PP 402 (113.31).
Dhillon (1994) reported good x average and good x
poor combinations resulted in high SCA effects for
dry matter content. Singh and Hundal (2001) reported
the highly significant SCA effects in the cross Lt-2 x
S-2545 for dry matter followed by MS-12 x ELS-82
and Punjab Guchhedar x Lorai. They also observed
that the GCA combinations resulting in high SCA
effects were mostly involving good x poor combiners.
Park and Takahasi (1980) reported that hybrids were
intermediate to their parents for the trait capsaicin
content. Lohithaswa et al. (2000) observed that the
cross Pant C-1 x Pusa Jwala had maximum value of
SCA effects for capsaicin content. Singh and Hundal
(2001) observed the cross Punjab Guchhedar x S-2545
as the best specific combiner for capsaicin content
followed by MS-12 x Punjab Surkh and Lt-2 x I-16.
They also observed that good x poor and poor x
average GCA combinations resulted in high SCA
effects. They also recorded highly significant SCA
effects in the cross Lt-2 x RHCH for oleoresin
followed by MS-12 x S-2530 and MS 12 x Lorai.
They observed that good x good and good x poor
combinations resulted in high SCA values for
oleoresin content. Singh and Hundal (2001) also
observed highly significant SCA effect in the cross
Lt-2 x ELS-82 for capsaicin in oleoresin followed by
Punjab Guchhedar x S-2529 and Punjab Guchhedar x
Ooty Round. They also revealed good x good and
poor x average GCA combinations resulted in high
SCA effects for capsaicin in oleoresin and poor x poor
GCA combinations resulted in high SCA effects for
colouring matter in oleoresin. Similarly, et al. (2005)
reported the crosses Tiwari x Arka Abhir, Tiwari x
ArkaLohit and RHRC-50-1 x PMR-57 having
significant SCA effects for oleoresin content. They
also identified the crosses PMR-14 x Byadgi Kaddi,
PMR-19 x PMR-39 and Tiwari x Punjab Guchhedar
having significant SCA effects for colouring matter
content. Prasath and Ponnuswami (2008) reported
that the cross Bydagi Kaddi x Co 4 had the highest
SCA effects for oleoresin content followed by Arka
Lohit x S 1 and Arka Lohit x Arka Abhir. They also
