摘要
木瓜是包括印度在内的世界热带和亚热带地区最重要的水果作物之一。虽然印度产量居世界首位,但由于番木瓜环斑病毒(PRSV-P)的高发病率,与其他国家相比,产量较低。由于Carica属栽培品种均对PRSV易感,对15个Arka prabhax V. cauliflora属间杂交后代和85个Arka prabhax V. cundinamarcensis属间杂交后代进行了形态、果实和产量性状与PRSV- P耐病性的比较研究。在15个子代中,7个‘Arka prabhax V. cauliflora即IGHF1S4-1, IGHF1S4-12, IGHF1S4-13, IGHF1S4-14, IGHF1S4-15, IGHF1S4-17, IGHF1S4-18;在85个子代中,6个‘Arka prabhax V. cundinamarcensis即IGHF1S1-17, IGHF1S1-19, IGHF1S6-20, IGHF1S2-14, IGHF1S5-12和IGHF1S5-14记录了理想的性状,如初结实天数(240至250天),果实高度(48至74厘米),株高(175至200厘米),树干周长(37至48厘米)。果实重(1133.67 ~ 2202.00 g)、果肉厚度(2.45 ~ 4.05 cm)、TSS(11.50 ~ 13.80ºBrix)、果实/树数(40 ~ 58)和产量(45.00 ~ 78.20 kg/树),以及抗PRSV能力和病分(叶片上只有几个小的褪绿斑点)。这些后代被选择并传递给下一代(F2)。利用SSR标记(mCpCIR59)对杂种性进行了验证。
Evaluation of intergeneric F1 hybrid progenies of papaya (Arka Prabhath x Vasconcellea cauliflora and Arka Prabhath x Vasconcellea cundinamarcencis) for morphological, fruit and yield traits coupled with PRSV tolerance
Papaya is one of the most important fruit crops of tropical and subtropical regions of the world including India. Though India stands first in production in the world, the productivity is low as compared to other countries due to high incidence of papaya ring spot virus (PRSV-P) attack. As all the cultivated varieties under genus Carica are susceptible to PRSV, investigations were carried out to evaluate fifteen intergeneric hybrid progenies of Arka Prabhath x V. cauliflora and eighty-five progenies of Arka Prabhath x V. cundinamarcencis for morphological, fruit and yield traits coupled with PRSV- P tolerance. Out of fifteen, seven progenies of ‘Arka Prabhath’ x V. cauliflora viz., IGHF1S4-1, IGHF1S4-12, IGHF1S4-13, IGHF1S4-14, IGHF1S4-15, IGHF1S4-17, IGHF1S4-18 and out of eighty-five, six progenies of ‘Arka Prabhath’ x V. cundinamarcensis viz., IGHF1S1-17, IGHF1S1-19, IGHF1S6-20, IGHF1S2-14, IGHF1S5-12 and IGHF1S5-14 recorded desirable traits such as days to first fruiting (240 to 250 days), bearing height (48 to 74 cm), plant height (175 to 200 cm), trunk circumference (37 to 48 cm), fruit weight (1133.67 to 2202.00 g), pulp thickness (2.45 to 4.05 cm), TSS (11.50 to 13.80 ºBrix), fruits/tree (40 to 58) and yield (45.00 to 78.20 kg/tree) coupled with PRSV tolerance with disease score1 (only a few tiny chlorotic spots on leaves). These progenies were selected and forwarded for next generation (F2). The hybridity was also confirmed using SSR marker (mCpCIR59).
