“…The hybrid H1470 x H1236 reported highest specific combination for micronaire value, which was a combination of poor x poor general combiner parents indicating that non-additive type gene action to be more important for improvement of this character. These findings are in confirmation with the findings of Karademr and Gencer (2010), Anandan (2010) and Sawarkar et al (2015). The values for the heterosis of individual crosses were recorded for all nine characters presented in Table 7.…”

“…However, in general the heterotic value for lint index obtained a marked increase in seed index. Similar results were reported by Hussain et al (2009), Basal et al (2011) and Sawarkar et al (2015). The crosses, namely H1464 x H1098-I (12.47), H1477 x H1236 (9.45) and ISR12 x H1226 (9.04) revealed higher heterosis over standard check for 2.5% span length.…”

“…Among these hybrids, five hybrids H1470 x H1236 (45.04%) followed by H1470 x H1098-i (37.84%), H1476 x H1226 (22.82%), AC726 x H1236 (22.57%) and H1464 x H1236 (12.64%) exhibited positive and best heterotic effects over the commercial check HHH 223 for seed cotton yield. Heterosis for seed cotton yield and other related characters in upland cotton has also been reported earlier by Rajamani et al (2009), Patil et al (2011), Jaiwar et al (2012), Sawarkar et al (2015) and Sharma et al (2016). Maximum heterosis over check HHH223 for lint yield was recorded in crosses H1470 x H1236 (38.28%), H1470 x H 1098-i (36.62%) and AC726 x H1236 (25.12%).…”

The cultivated Gossypium spp. represents the most important, natural fibre crop in the world. Breeding for high cotton yield is still the primary goal of cotton breeding programs, but improving fibre quality has become increasingly important. The enhancement of fibre quality traits like fibre length, strength, and fibre fineness is an essential requirement for the modern textile industry. The objective of this study was to facilitate the selection in cotton breeding program and estimate the general combining ability (GCA) of the parents and specific combining ability (SCA) of hybrids considered for the development of high yielding and better fiber quality in early generations. The study was carried out at cotton research area, CCS Haryana Agricultural University, Hisar (India) during 2014 and 2015 kharif season. Fifteen cotton lines (which have maximum diversity) and four testers (which are known as well adapted and high yielding) were crossed in a line x tester mating design in 2014. Nineteen genotypes and 60 F1 hybrids were planted in the randomized complete block design with three replications at the same experimental area in 2015. The ratio of δ2 GCA /δ2 SCA was less than unity for all the nine characters indicating preponderance of non-additive gene action (dominance and epistasis), which is an important in exploitation of heterosis through hybrid breeding. The best general combining ability was detected from the parent H1470 for seed cotton yield, H1464 and H1098-i for fiber quality traits. SCA was significant for AC726 x H1236, ISR12 x H1226, HR1 x H1117 hybrid combinations for yield and fiber quality. The crosses H1470 x H1236 and H1470 x H1098-i were reported good heterosis for seed cotton yield as well as for fibre quality, selected the best hybrids were H1464 x H1098-i and H1463 x H1226. These cross combinations involved at least one parent with high or average GCA effect for a particular trait. The cross combination involving H1470, H1098-i and H1464 parents’ recorded significant positive heterosis with acceptable SCA effect for both yield and fibre quality parameters. This investigation concluded that the parents H1470, H1098-i and H1464 can be used in hybrid development programme with better fibre quality.

Two‐year study on combining ability and heterotic potential in functional traits under salt stress in upland cotton (Gossypium hirsutum)

Salt tolerance is a physiologically and genetically complex trait controlled by multiple genes. To analyze the genetic basis of salt tolerance we evaluated 18 F 1 along with their nine parents under three salt stress levels i.e. control, 10 dS m −1 and 15 dS m −1 in the summer of 2017 and 2018. Data were recorded for the number of bolls, seed cotton yield, boll weight, Na + , K + , K + /Na + ratio, H 2 O 2 , SOD, POD, CAT and TSP. Line × tester analysis indicated that the contribution of lines was greater than testers. Except for Na + , most of the traits were controlled by non-additive genes. With the rise of salt stress, SCA variances increased and were higher than GCA variances for most of the traits indicating the traits were controlled by a few largely dominant genes. KEHKSHAN, FH-118 and FH-114 were found good general combiner whereas the cross KEHKSHAN × FH-114 was a good specific combiner and also indicated significant better parent heterosis for most traits during two years under salt stress and can be utilized in a breeding programme for salt tolerance.
