“…An examination of gca estimates revealed that among these two female parents Sheetal (2.700) and Punakhira (1.191) as well as three male parents Fansu local (1.604), VRC-19 (0.817) and AAUC-2(0.692) exhibited highest sca effects These parents were exhibits good general combining ability. These results were in similar line with Pati et al (2015) [13] and Reddy et al (2014) [15] . A perusal of estimates of sca effects of hybrids revealed that ten hybrids showed significant positive sca effects, among these Puna khira x Fansu local (2.221) and Shubhnagi x AAUC-1(2.092) recorded highest significant positive sca effects.Bhutia et al (2017) [2] and Naik et al (2018) [10] obtained similar findings for this trait.…”

The experimental material for the present study comprised of F1 population of twenty four crosses, developed by crossing four female parents viz., Sheetal, Shubhangi, Himangi, and Puna khira of cucumber with six male parents viz., AAUC-2, DC-2, AAUC-1, VRC-19, DARL-103 and Fansu local. The experiment was laid out with 24 F1s, 4 females 6 males and one check Konkan kakadi in Randomized Block Design (RBD) with two replications during the kharif 2017.Observations were recorded on thirteen different quantitative characters The perusal of estimates of gca effects revealed that two female parents viz., sheetal (0.572), Puna khira (0.235) and two male parents Fansu local (0.596) and VRC-19 (0.376) exhibited significant positive gca effect in kharif 2017. This showed that these parents were good general combiner for the marketable yield vine -1 . The best three hybrids with respect to marketable yield vine -1 based on significant positive sca were viz., Sheetal x Fansu local (0.942), Shubhangi x DC-2 (0.532), Puna khira x VRC-19 (0.484). A perusal of the data indicated that the estimates of σ 2 SCA were higher in magnitude as compared to σ 2 GCA (average) both in females and males for the traits under study viz., days to first male flower appearance, days to first female flower appearance, nodal position of first female flower, days to first picking, fruit length and diameter, average fruit weight, marketable yield vine -1 , harvest duration and total soluble solids. In all the traits studied, the SCA variances were higher than GCA values, indicated the role of non-additive gene action.While lower magnitude of SCA showed additive gene action. The heritability estimates from different variance components having very high heritability obtained for number of marketable fruits vine -1 (69.02%) and number of primary branches plant -1 (94.40%).

“…Cucumber is indigenous to India (SEBASTIAN et al, 2010). India being native palce of cucumber possesses vast genetic variability for its vegetative and fruit characters (PATI et al, 2015b). The fruits are also used as an astringent, antipyretic and are good for people suffering from constipation, jaundice and indigestion.…”

Understanding the level of genetic diversity and structure of landraces is essential for economical use of genetic resources. In the present study, we investigated the genetic diversity of 36 representative sample of cucumber genotypes based on 10 quantitative traits and 17 polymorphic simple sequence repeat (SSR) markers. Our result revealed variability in flowering behavior, growth habit and fruit characters. We found that the traits, days to opening of first female flower varied from 39.03 to 51.94, fruit length 6.09 to 30.01(cm), fruit weight 104.39 to 277.05(g) and yield per plant 699.38 to 1670.93(g). Genetic distance based on 17 SSR markers among 36 genotypes was quantified ranging from 0.03 to 0.70 indicated a wide diversity among the genotypes selected for evaluation in the present study. These primers produced 2-4 number of alleles with an average 2.76. Polymorphism information content varied from 0.005 to 0.550 with an average of 0.348. The observed heterozygosity mean was 0.098, while gene diversity or expected heterozygosity was 0.625 to 0.057. The distinct genotypes found in this study based on 406
