The study was conducted using six testers, of which two (KAU M-1 and KAU M-2) were completely bacterial wilt resistant, and four genetic male sterile lines (GMS), in a line x tester model and further the F1 hybrids were evaluated in a bacterial wilt sick plot for various vegetative, floral and yield parameters along with their response to wilt incidence. Field evaluation for bacterial wilt resistance revealed that out of 24 hybrids, 13 hybrids involving KAU M-1 and KAU M-2 as testers exhibited bacterial wilt resistance. Analysis on heterosis for various characters viz., vegetative, floral, yield and total carotenoids content showed significant heterosis for many of the hybrids over mid parent, better parent and the check variety. The highest standard heterosis for yield was observed for the interspecific hybrid KU Ms-6 xx KAU M-47 (190.84%) followed by an intraspecific hybrid KAU Ms-42 x KAU M-2 (70.93%). Based on the wilt resistance and heterotic performance, these two hybrids can be suggested for commercial cultivation in wilt affected areas.

“…According to Panwar et al, (2013) in marigold, 10 hybrids, 17 hybrids and 1 hybrid showed significant and positive heterobeltiosis, average and standard heterosis respectively. Bhargav et al, (2018) observed 20 crosses with significant positive relative heterosis and two crosses with significant negative relative heterosis among 30 crosses in China aster.…”

“…Kulkarni et al, (2015) observed four best hybrids, out of twenty, to have high heterosis over mid parent and better parent for vase life in China aster. Out of 30 crosses made by Bhargav et al, (2018), four crosses showed significantly positive heterosis in China aster.…”

“…It was observed that the hybrid MSC3 x PNG had the highest heterosis for number of flowers per plant and flower duration over the standard parent. Bhargav et al, (2018) reported that relative heterosis ranged from -60.88 (L5 x T2) to 108.79 (L6 x T5) and 6 crosses showed significant positive relative heterosis in China aster (Table 3). From garland making or loose flower market point of view, the weight of the flower is the dominant factor as higher the flower weight, more the price and market value.…”

Despite the economic significance of periwinkle [Catharanthus roseus (L.) G. Don] the existence of genetic variation in traits have been largely unexplored and very little attempt has been done to improve its genetics for ornamental prospective. An experiment was conducted at the research farm of Punjab Agricultural University, Ludhiana, Punjab during 2019 to 2021 using 6 inbred lines of periwinkle to develop 30 F1 populations in full-diallel fashion. The highly significant positive heterobeltiosis was recorded in the progeny of Vi-29 × Vi-14-3 for leaf breadth, follicle length, number of flowers per plant and number of seeds per follicle. The cross combination Vi-13-2 × Vi-29 was recorded significantly high heterobeltiosis for plant height and plant spread. The minimum heterobeltiosis was recorded for plant spread and follicle length in cross Vi-14-3 × Vi-15-1. The highest mean performance of the parents reported in Vi-15-1 for plant spread, internode length, flower diameter, number of flowers per plant, follicle length and number of seeds per follicle. As per the results among the cross combinations superior mean performance was observed in the Vi-15-1 × Vi-14-3 for leaf length and number of flowers per plant. These findings suggest that hybridization is an efficient way of contributing genetic variability in periwinkle for landscape utilization.
